A highly transparent cellulose film with a high built-in haze is emerging as a green photonic material for optoelectronics. Unfortunately, attaining its theoretical haze still remains a challenge. Here, we demonstrate an all-cellulose composite film with a 90.1% transmittance and a maximal transmission haze of 95.2% close to the theoretical limit (∼100%), in which the entangled network of softwood cellulose fibers works as strong light scattering sources and regenerated cellulose (RC) with undissolved fibril bundles functions as a matrix to simultaneously improve the optical transparency and transmission haze. The underlying mechanism for the ultrahigh haze is attributed to microsized irregularities in the refractive index, arising primarily from the crystalline structure of softwood fibers, undissolved nanofibril bundles in RC, and a small number of internal cavities. Moreover, the resulting composite film presents a folding resistance of over 3500 times and good water resistance, and its application in a perovskite solar cell as an advanced light management layer is demonstrated. This work sheds light on the design of a highly transparent cellulose film with a haze approaching the theoretical limit for optoelectronics and brings us a step further toward its industrial production.

Transparent lignocellulose nanopaper (LNP) has been demonstrated to be a promising candidate light-management material for next-generation optical engineering applications. Similar to its role in plant cell walls, lignin serves as a vital functional component in LNP matrices. However, its intrinsic light absorption property renders LNP undesirable for a range of optical management systems. Here, a highly efficient, controllable and ecofriendly lignin modification strategy is developed for modulating the optical performance of LNPs by taking advantage of the beneficial synergistic effect of H 2 O 2 and UV light in selectively eliminating lignin chromophores . The obtained lignin-modified LNP features not only a high visible light transmittance (89%) but also a high haze (90%) and excellent UV-shielding capacity, owing to the well-preserved lignin aromatic skeleton structures after lignin modification. Furthermore, patterning is easily achieved on hot-pressing-induced densified LNPs through a selective lignin modification approach, which endows LNPs with intriguing optical designability. Benefitting from the multifunctionality of lignin components for nanopaper matrices, patterned LNPs demonstrate outstanding water and thermal stability, barrier properties, durability and biodegradability, which are of great significance for practical applications. Furthermore, we demonstrate the great applicability of this optically designable and multifunctional LNP as a light-management material for energy efficient buildings by highlighting its attractive sun- and indoor- light managing effects, effective thermal insulation , as well as superior durability for long-term use. In combination with its efficient, ecofriendly and controllable production, this novel high-performing LNP holds great potential in many other applications that require light-management structural materials, such as optoelectronic and sensing devices.

Fibrillated cellulose-based nanocomposites can improve energy efficiency of building envelopes, especially windows, but efficiently engineering them with a flexible ability of lighting and thermal management remains highly challenging. Herein, a scalable interfacial engineering strategy is developed to fabricate haze-tunable thermal barrier films tailored with phosphorylated cellulose nanofibrils (PCNFs). Clear films with an extremely low haze of 1.6% (glass-scale) are obtained by heat-assisted surface void packing without hydrophobization of nanocellulose. PCNF gel cakes serve here as templates for surface roughening, thereby resulting in a high haze (73.8%), and the roughened films can block heat transfer by increasing solar reflection in addition to a reduced thermal conduction. Additionally, obtained films can tune distribution of light from visible to near-infrared spectral range, enabling uniform colored lighting and inhibiting localized heating. Furthermore, an integrated simulation of lighting and cooling energy consumption in the case of office buildings shows that the film can reduce the total energy use by 19.2–38.1% under reduced lighting levels. Such a scalable and versatile engineering strategy provides an opportunity to endow nanocellulose-reinforced materials with tunable optical and thermal functionalities, moving their practical applications in green buildings forward.

The functional paper holds significant potential in some special fields, which has achieved great development. Nevertheless, using cellulose paper to fabricate functional paper, which integrates transparency, robustness, flexibility, shape memory, and sustainability, remains a challenge. Herein, the vitrimer precursor was vacuum impregnated into cellulose paper and then in-situ polymerized to develop a vitrimer-cellulose paper (VCP) with transparency, shape manipulation, robustness, and sustainability. Taking advantage of the vitrimer’s dynamic performance, the resulting VCP demonstrated excellent optical transparency (transmittance of 84%, haze of 75%), enhanced mechanical strength (tensile strength of 80.5 MPa), chemical resistance, thermal-triggered shape manipulation, and reprocessing. Noteworthily, VCP possessed outstanding light management capability with effective light propagating and scattering performance. Furthermore, VCP laminate showed increased mechanical property with the increased layers, and it can be reprocessed to a bulk composite after crushing. These incorporated merits of VCP make a promising candidate for light management and sustainable building application.

Photovoltaic (PV) modules are not only an opto-electrical system, but also opto-thermal one, where the optical, electrical, and thermodynamic domains are strongly coupled. The means to suppress both light and heat losses in PV modules remains undeveloped. Herein, a universal route to realize both radiative cooling and light management via the ultra-broadband versatile textures is proposed, originating from the interaction with the visible, near-infrared, and mid-infrared electromagnetic waves (EMWs) via geometric, diffractive, and subwavelength optical effects. The sol–gel imprinted ultra-broadband textures exhibited a near-unity infrared emissivity over 0.96 at the atmospheric window between 8 to 13 μm for radiative cooling, and a solar transmittance and haze above 0.94 and 0.95 at the wavelengths from 350 to 750 nm, respectively, for light management. Applying the ultra-broadband textures imprinted glass to silicon PV modules as an encapsulant cover, the short-circuit current and conversion efficiency were increased by 5.12 and 3.13% in relative terms, respectively. The fabrication of such ultra-broadband versatile textures was photolithography-free, scalable, and PV industry compatible, which provided a cost-effective, long-term durable, and energy-efficient means to both light and thermal management through ultra-broadband matter-EMW interaction not only in PV modules, but also various opto-electro-thermal devices.

Silica glass, known for its brittleness, weight, and non-biodegradable nature, faces challenges in finding suitable alternatives. Transparent wood, made by infusing polymers into wood, shows promise but is hindered by limited availability of wood in China and fire risks associated with its use. This study explores the potential of utilizing bamboo, which has a shorter growth cycle, as a valuable resource for developing flame-retardant, smoke-suppressing, and superhydrophobic transparent bamboo. A 3-layered flame-retardant barrier, composed of a top silane layer, an intermediate layer of SiO2 formed through hydrolysis-condensation of Na2SiO3 on the surface, and an inner layer of Na2SiO3, has been confirmed to be effective in reducing heat release, slowing flame spread, and inhibiting the release of combustible volatiles, toxic smoke, and CO. Compared to natural bamboo and other congeneric transparent products, the transparent bamboo displays remarkable superiority, with the majority of parameters being notably lower by an entire order of magnitude. It achieves a long ignition time of 116 s, low total heat release (0.7 MJ/m2), low total smoke production (0.063 m2), and low peak CO concentration (0.008 kg/kg). Moreover, when used as a substrate for perovskite solar cells, the transparent bamboo displays the potential to act as a light management layer, leading to a marked efficiency enhancement of 15.29%. The excellent features of transparent bamboo make it an enticing choice for future advancements in flame-retardant glasses and optical devices.

A facile approach was developed for fabricating transparent-hazy multiscale cellulose films . Initially, a mixture of cellulose micro- and nanomaterials (CMNM) was prepared through rapid succinylation of bamboo cellulosic materials at room temperature for 10 min, followed by mechanical disintegration in a food blender for an additional 10 min. This process yielded multiscale transparent films as water evaporated. By manipulating molar ratios of succinic anhydride (SA) to anhydroglucose unit (AGU) during esterification, the multiscale films possessed a haze ranging from 59.2 % to 92.3 %, while retaining high transparency of up to 90.5 %. The dual micro- and nano-network structure endowed the films with excellent flexibility and mechanical performance (tensile strength of 105 MPa and modulus of 6.0 GPa). The developed multiscale films demonstrated to effectively enhance the luminescence uniformity of the light-emitting diode (LED) light while exhibited a notable anti-glare effect, suggesting its potential of these films for various light management applications.

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.

Dielectric encapsulation materials are promising for solar cell areas, but the unsatisfactory light-management capability and relatively poor dielectric properties restrict their further applications in photovoltaic and microelectronic devices. Herein, an interface fusion strategy to engineer the interface of MOF (UiO-66-NH 2 ) with anhydride terminated imide oligomer (6FDA-TFMB) is designed and a novel MOF cluster (UFT) with enhanced forward scattering and robust porosity is prepared. UFT is applied as an optical and dielectric modifier for bisphenol A epoxy resin (DGEBA), and UFT epoxy composites with high transmittance (>80%), tunable haze (45–58%) and excellent dielectric properties can be prepared at low UFT contents (0.5–1 wt%), which delivers an optimal design for dielectric encapsulation systems with efficient light management in solar cells. Additionally, UFT epoxy composites also show excellent UV blocking, and hydrophobic, thermal and mechanical properties. This work provides a template for the synthesis of covalent bond-mediated nanofillers and for the modulation of haze and dielectric properties of dielectric encapsulation materials for energy systems, semiconductors, microelectronics, and more.

The flexible transparent electrode is a crucial component of wearable photoelectric devices, and has a significant influence on the performance and development of wearable devices. Here, a phosphor/polyimide/polyurethane@silver composite nanofiber (NF) web electrode was fabricated by electrospinning and magnetron sputtering for wearable photoelectric devices. The electrode demonstrated a promising light management ability with converting ultraviolet light to visible light, high conductivity with sheet resistance of 22.1 Ω/square, and high transparency with transmittance of over 80%. Besides, the electrode possessed an excellent stretched capacity with tensile strain of over 100%, and tensile stability with the resistance increased by ∼75% after 500 stretching cycles at the tensile stain of 50%. As a result, a flexible perovskite solar cell (PSC) was assembled by using the NF web electrode, and possessed the power conversion efficiency of 3.47%, which is higher than that of PSCs based on electrodes without phosphor. Furthermore, the flexible PSCs exhibited promising mechanical stability under bending, and could serve as wearable devices. This work provides a feasible and promising method to prepare lightweight, stretchable, light management, and transparent electrodes for photoelectric devices, and may facilitate the development of wearable photoelectric devices.

Biodegradable agriculture films with the function of light conversion to better match the spectrum of plant photosynthesis are critical for achieving sustainable development and boosting plant production. In this work, transparent light conversion cellulose composite films were prepared by incorporating blue and red emitting carbon dots (B&R-CDs) into a regenerated cellulose (RC) film, followed by covering with a silicone acrylic emulsion (SAE) layer to enhance water resistance. SEM observations showed that the surface of the cellulose composite film was smooth. The fabricated SAE/B&R-CDs/RC film featured a high average transmittance (89.7 %) in the visible region. Its photosynthetic photon flux density (PPFD) was 4.7 % higher than that of the film without CDs. The cellulose composite film exhibited a tunable water vapor transmission rate (WVTR) by changing the thickness of the SAE layer. The cellulose composite film possessed a high tensile strength of 60 MPa and an elongation at break of 13.6 %. In particular, despite the presence of the SAE, the SAE/B&R-CDs/RC film fully degraded after 112 days of soil burial. This study opens up a novel avenue for the development of biodegradable and light-conversion functional agricultural films.
