Perovskite solar cells (PSCs) have become a promising solar energy utilization technology due to their high energy conversion efficiency and low preparation cost. However, the inherent instability under UV illumination limits their practical applications. In this work, we developed a new approach to fabricate functional cellulose paper (FTH paper) with high transparency, high haze, and UV-blocking, which can be used to extend the lifespan of PSCs. When the impregnation amounts of carboxymethyl cellulose and tannic acid were 16 wt% and 0.7 wt%, the light transmittance and UV-blocking performance reached 86.8% (at 600 nm) and 83.1% (at 320 nm), respectively, while maintaining a haze of 71.5%. After protonation and desalination treatment, the FTH paper exhibited good water resistance and mechanical properties (71.49 MPa, 2156 folding cycles). More importantly, FTH paper coating can significantly improve optical path length and the UV-stability (improved by 26% after 100 h) of PSCs. This study not only provides a simple and effective strategy to improve the properties of PSCs but also opens the way for high-value utilization of paper materials.

Transparent building envelopes are valued for ample natural daylight, yet they face issues of glare, privacy concerns, and excessive solar heat gain. Existing anti-glare or radiative cooling coatings typically either reduce visible transmittance or fail to combine high haze with high infrared emissivity. We have developed a room-temperature-curing FPHS coating composed of polyethoxysiloxane (PEOS), hydroxyl silicone oil, and 3,3,3-(trifluoropropyl)trimethoxysilane (TTMS). Utilizing in-situ nanoparticle formation and microphase separation technology, this coating achieves a visible light transmittance of 90.43%, a haze of 84.64%, and an emissivity of 94.06% within the 8-13 μm atmospheric window. These unique optical properties enable a maximum daytime temperature reduction of 14.6 °C, while the low-surface-energy surface ensures self-cleaning and dust-repellent properties. When coated onto photovoltaic panels, the FPHS coating reduces operational temperatures of photovoltaic modules, elevates short-circuit current, and improves overall power conversion efficiency. It delivers a scalable, zero-energy strategy to simultaneously realize glare suppression, privacy modulation, and passive radiative cooling for transparent building envelopes and optoelectronic devices.

Optical antiglare films with high light transmittance and high haze are capable of mitigating the adverse effects of glare on eyes and offering a healthy visual experience. However, the haze increase is always accompanied with the severe loss of the light transmittance, posing a considerable challenge to simultaneously achieving high transmittance and high haze. In this work, a polyvinylbutyral (PVB) nanofibers-based polydimethylsiloxane (PDMS) film featuring of matched refractive indices, loosely fiber stacked density in PDMS, and appropriate fiber diameter close to the visible light wavelength, was prepared with exceptional antiglare property. Subsequently, it was further air sprayed with a hydrophobic F17@SiO 2 coating to endow the P-PVB/F17@SiO 2 composite film superhydrophobicity and self-cleaning with the water contact angle reaching 170.4°, expanding its practical applications. By employing a trimodal light regulation strategy, including Rayleigh scattering of nanoparticles, light reflection induced by micro-tunnels, and Mie scattering caused by nanofibers, the P-PVB/F17@SiO 2 film demonstrated an excellent transmittance of 90.73% and an admirable haze of 94.5%. Therefore, based on the straightforward, large-scale, cost-effective manufacturing, this work proposes a reliable way to achieve optical antiglare film with effective light regulation, which shows a great potential for applications in smart mobility, intelligent buildings, and flexible electronics, etc.

Light management films that can alter the transmission light path while maintaining the total luminous flux, especially introducing natural biological macromolecules for sustainable development of comfortable lighting, energy-efficient buildings, and optoelectronic devices, etc. However, grand challenges remain in preparing high transmittance and high haze films while maintaining stretchability and flexibility to meet application requirements. Herein, poly(styrene- co -acrylic acid) (PS- co -PAA) was synthesized and electrospun to obtain grid-like patterned nanofibers, and then infiltrated by polyvinyl alcohol (PVA) solution to prepare nanofiber-based hydrogel. The hydrophilic acrylic segments of PS- co -PAA enhanced the hydrogel infiltration, while the hydrophobic styrene segments facilitated the formation of numerous pores, endowing the film with effective light scattering without severe light loss. Notably, chia seeds mucilage (CSM), rich in natural polysaccharide with polyhydroxyl groups, introduced into the hydrogel for the resultant PVA-PA-CSM film with remarkable light transmission of 82.6 %, admirable haze of 95.6 %, harmful blue light blocking and superior tensile strain of 516.6 % favorable for adjustable light transmittance and haze. Additionally, self-adhesion, self-supporting, twisting, knotting, puncture resisting and effective temperature regulation were conferred to the film. Thus, our work provides novel insights into the fabrication of renewable light management films serving as next-generation optical materials, with broad potential for intelligent lives.

Films with the capacity for photoluminescence and haze, which can convert UV to visible light and enhance light management, are of great importance for optoelectronic devices. Here, taking advantage of the inherent fluorescence and self-assembly properties of lignin, we have developed a sustainable lignin-derived multifunctional dopant (L-MS-NPs) for fabricating optical films with haze, fluorescence, and room-temperature phosphorescence (RTP) together with poly(vinyl alcohol) (PVA). The optical films are used to improve the light-harvesting efficiency of solar cells. Specifically, attributed to the robust morphology in the film matrix, L-MS-NPs cause a rough morphology in the surface of an L-MS-NPs/PVA composite film, which eventually triggers the great optical haze. Additionally, L-MS-NPs inherit fluorescence properties from lignin and show fluorescence emission when embed in the film matrix. Moreover, the PVA film matrix can stabilize the excited triplet state, which finally induces RTP of L-MS-NPs. The combined haze, fluorescence, and RTP properties of the L-MS-NPs/PVA composite film enhances the power conversion efficiency (PCE) of dye-sensitized solar cells from ∼3.9 to ∼4.1%.

Well-dispersed cesium-doped WO3 (CWO) nanocrystals are an attractive candidate as hosts that exhibit excellent near infrared-shielding ability owing to two kinds of absorptions: localized surface plasmon resonance absorption around 900 nm and small polaron absorption near 1800 nm. In this work, a simple thermal reduction method was introduced to synthesize a CWO powder, which was further dispersed by bead milling to obtain a CWO nanodispersion liquid. The CWO nanodispersion liquid can be employed to make a unique nonlinear optical foil with 70% visible transmittance and a near infrared transmittance less than 10%, while maintaining a high transparency with less than 1.0% haze. However, the main issue concerning CWO nanoparticle-based polymer foils is the detrimental photochromic effect under strong ultraviolet (UV) irradiation, which hampers their extensive application in energy-saving windows, such as in automobiles and architecture. Herein, the photochromic effect is largely relieved by embedding CWO nanoparticles into inert polyethylene terephthalate (PET) instead of mixing with resins like polyurethane or acrylic resin, and the final organic–inorganic nonlinear optical foils exhibit almost no coloration under strong UV illumination. Therefore, this study provides a new insight into making hybrid foils with high stability, transparency and multifunctionality in the optical and magnetic fields.

The proliferation of flexible electronic products derived from petroleum substrates in the market has exacerbated environmental pollution stemming from electronic waste generation. As a result, there is an increasing demand for cellulose nanofiber substrates that are green and degradable. However, substantial challenges remain in addressing the hydrophilicity of nanocellulose substrates and optimizing their optical properties for commercial viability. In this study, we propose a multifunctional composite film material through the use of amidation modification and biomineralization technology. We successfully grafted highly carboxylated transparent oxide nanocellulose (TCNF) and octadecylamine (ODA) using carefully designed amidation conditions. Through the carboxyl group after amination, we were able to generate amorphous calcium carbonate (ACC) in situ, resulting in the creation of a flexible, sustainable, and transparent TCNF/ODA/CaCO 3 composite film with high hydrophobicity and haze. This was confirmed by a water contact angle value of 138.21° and a haze value of 84.8%. The composite film exhibits low surface energy and high dual-scale surface roughness, while its internal structure is relatively porous and loose, but still possesses multi-scale interface interactions. We demonstrate a strong correlation between the multifunctional properties and structural properties of the composite films in this work, thereby achieving effective light management applications in solar cells. Our findings are expected to provide new insights and ideas for the design of multifunctional green flexible solar cell device substrate materials.

Anti-blue light films with high transparency and low haze that completely originate from renewable and biodegradable biomass materials for eye protection is a growing trend with great demand in the near future. Therefore, in this study, a natural bioactive ingredient, lutein, was incorporated into the cellulose matrix via a green and facile adsorption strategy to prepare biodegradable ultraviolet (UV) and blue light filters. The lutein/carboxymethylated cellulose films (L-CCFs) displayed high anti-UV capacity, with UV-A and UV-B blocking ratios of 52.7 %-90.9 % and 44.1–85.2 %, respectively. The composite films could block 83.1–97.8 % of blue light in the 400−500 nm region while maintaining high transparency (86.6–89.3 %) and low haze (2.1–2.6 %). By light absorption, the films can effectively shield blue light emitted by light-emitting diodes, sunshine, lighting systems, mobile phone, and computer screens. Quite encouragingly, the addition of lutein significantly increased the water contact angle from 40.1 to 70.5° and the composite films have excellent liquid barrier properties. Meanwhile, these films exhibit higher light stability than lutein powders, thus greatly extending the service life of the film as a blue light shielding material. Moreover, the films have excellent mechanical strength (>110 MPa) and biodegradability. These films prepared entirely from natural resources offer great application value in the fields of electronic screen films and spectacle lenses.

The increasing demand for improving the performance of optical devices and the development of nanotechnology have driven research on diffusion films. The preparation of diffusion films with well-defined microstructures can achieve uniform diffusion and scattering of light, thereby improving the efficiency and performance of optical devices. In this study, diffusion films with high transmittance and haze were prepared using PMMA@TiO2@SiO2 (P@T@S) composite microspheres, and the PMMA microspheres and nanoparticles were combined through electrostatic attraction. As compared with PMMA microspheres, the P@T@S composite microspheres displayed better heat resistance as well as swelling resistance. Optical performance data showed that the P@T@S diffusion film had the perfect optical performance with a transmittance up to 90.5% and a haze of 88.3%. The excellent light diffusion effect of the P@T@S diffusion film was experimentally demonstrated, with the light through the film not only displaying the largest area but also maintaining a relatively high brightness. Our findings can provide reference and guidance for further development of light diffusion films, which are of potential application in optoelectronic devices.

This study presents the particle size distribution and respiratory deposition estimates of airborne perfluoroalkyl acids (PFAAs) during the haze period. Size-segregated haze aerosols were collected from an urban location in Shanghai using an eight-stage air sampler. The samples were analyzed for eight PFAAs using ultra-high-performance liquid chromatography tandem triple quadrupole mass spectrometry. The quantification results showed that the concentrations of particle-bound Σ 8PFAAs ranged from 0.26 to 1.90 ng m −3 (mean: 1.44 ng m −3 ). All of the measured PFAAs particle size distributions had a bimodal mode that peaked respectively in accumulation size range (0.4 < Dp < 2.1 μm) and coarse size ranges ( Dp > 2.1 μm), but the width of each distribution somewhat varied by compound. The emission source, molecular weight , and volatility of the PFAAs were important factors influencing the size distribution of particle-bound PFAAs. Of these compounds, PFUnDA presented a strong accumulation in the fine size range (average 75% associated with particles <2.1 μm), followed by PFOA (69%) and PFDA (64%). The human risk assessment of PFOS via inhalation was addressed and followed the same pattern as the size distribution, with a 2-fold higher risk for the fine particle fraction compared to the coarse particle fraction at urban sites. Approximately 30.3–82.0% of PFAA deposition (∑PFAA: 72.5%) in the alveolar region was associated with particles <2.1 μm, although the contribution of fine particles to the total PFAAs concentration in urban air was only 28–57% (∑8PFAAs: 48%). These results suggested that fine particles are significant contributors to the deposition of PFAAs in the alveolar region of the lung.

Renewable cellulose is an outstanding candidate to prepare biomass-based optical management films with tunable transparency and haze. Micro-scale and nano-scale cellulose derived from the parenchyma cells (PC) and bamboo fibers (BF) of Dendrocalamus sinicus was first separated and then subjected to succinic esterification and mechanical defibrillation using three different methods: ultrasonication, high-speed blending, and microfluidization. Sustainable multiscale optical management films with tunable haze were obtained by changing the weight ratios of micro/nanoscale cellulose. The PC-based micro/nano cellulose (MNC) films obtained by microfluidization with the highest content of nanoscale cellulose (96.5 %) displayed the highest light transmittance (89.4 %) and tensile strength (164.3 MPa) but the lowest haze (32.0 %) and anti-glare ability. The BF-based MNC films obtained by ultrasonication with the lowest content of nanoscale cellulose (20.4 %) but the highest content of microscale cellulose (79.6 %) showed the highest haze (96.7 %), a medium light transmittance (81.3 %), and the outstanding anti-glare effects. The MNC films with both high in transparency (84.8–87.5 %) and haze (81.5–88.4 %) along with good strength and flexibility can be obtained by tuning the bamboo components and mechanical defibrillation methods. This study provides a green and facile way to fabricate sustainable optical management films.

A delignified longitudinal-cutting poplar veneer-based epoxy resin composite (TLPE) with excellent transmittance, haze, flexibility and wood fiber art texture, that was prepared by delignifing longitudinal-cutting poplar veneer (LPV) and filling the delignified LPV with epoxy resin (ER). The TLPE has retained the porous structure and wood fiber art texture of LPV due to the fact that it is not completely filled with resin. The changed benzene skeleton and the ether (C-O-C) were found in the TLPE, that should be due to the chemical combination between the benzene of filled ER and the cellulose of delignified LPV, and the chemical reaction between the benzene and the cellulose yielded the C-O-C. Parts of the TLPE that are completely filled with the ER, that can reach a transmittance of approximately 90 % and a haze of approximately 90 %. Moreover, due to the combined action between the fibril of delignified LPV and the ER, the TLPE has high refractive index fluctuation in the perpendicular direction of fiber and excellent flexibility (the elongation at break: 15 %). When the TLPE is used as the building material, the TLPE can provide a comfortable lighting effect after the light passes through it, it can also accommodate various streamlined and natural artistic shapes with wood fiber art texture in buildings, and it can also achieve a balance between science and art in the building through its optical, styling, and textural advantages.
