The combination of photo-driven self-powered supplies and energy storage systems is considered as a promising candidate to solve the global energy dilemma. The photo-absorber and the energy storage material are integrated into the photocathode to effectively achieve a high-energy and high-efficiency energy system. In this work, we report the customized Janus-jointed photocathode design (integrating with highly efficient halide perovskite and tellurium composite electrode) and introduce it into the aqueous zinc–tellurium battery. The well-matched energy level of the Janus-jointed photocathode ensures the conversion of the photoenergy into electrical energy by transferring the photoexcited charge between each. As expected, in the photo-assisted recharging model, the decreased 0.1 V charge voltage and the extra 362 mA h g–1 at 100 mA g–1 demonstrated the significant merits of saving energy for such a photo-rechargeable Zn–Te (PRZT) battery. When the current density is 1000 mA g–1, the specific capacity of the prepared photocathode is 83% higher than that under dark conditions. More importantly, the photogenerated charge by the perovskite under light illumination could also directly photocharge the battery with no external current, indicating the self-powering traits. The rational design in this work is believed to provide a sustainable mode for efficient charging of the aqueous PRZT battery.

Summary The photo-responsive capability of lithium battery materials is a prerequisite to realize new-generation light-weight photo-rechargeable batteries. However, the photo-charging property is not available for common battery electrode materials such as LiFePO 4 . In this manuscript, we provide evidence that the halide perovskite material CH 3 NH 3 PbI 3 is able to activate the photo-charging properties of the lithium-ion battery electrode material LiFePO 4 . The photoelectrochemical measurement demonstrates that the photo-responsive property of the CH 3 NH 3 PbI 3 /LiFePO 4 composite is significantly improved; the photo-induced signals are neither observed in the individual halide perovskite nor the lithium battery material tested under the same condition. The first-principles calculations reveal strong interactions between the CH 3 NH 3 PbI 3 layer and the LiFePO 4 layer via the coordination between the Lewis acid and Lewis base species; this forms a heterostructure that assists the photo-charging process. We propose that the combination of halide perovskite materials and lithium battery electrode materials is a viable way to achieve light-weight photo-batteries. Suggestions to address the stability and voltage issues of the halide perovskite-based hybrid systems toward the photo-battery application are provided. This study facilitates the fundamental understanding of the integrated photo-rechargeable battery materials and highlights the importance of halide perovskite materials for the lithium-ion and photo-rechargeable batteries.

In light of the immense potential solid-state photo-rechargeable batteries hold in the efficient utilization of renewable solar energy, there is a rapidly growing demand for materials that possess both energy harvesting and storage capabilities. In this study, a solid-state photo-rechargeable battery has been designed based on the FTO(Fluorine-doped SnO 2 transparent conductive glass)/TiO 2 /Cs 3 Bi 2 Br 9 /Pt/FTO system, which achieves dual functions of photoelectric conversion and energy storage. The inorganic bismuth-based material employed in these batteries exhibits commendable cyclic stability. Under photo-rechargeable conditions, a single cell can maintain an open-circuit voltage as high as 0.45 V in the absence of illumination. By connecting multiple cells in series, we succeed in powering an LED (Light-emitting diode) continuously for 1 min without light exposure. The findings of this research open new avenues for the design and development of novel materials that could enable highly efficient solid-state photo-rechargeable batteries.

The development of self-chargeable lithium-ion batteries is of great significance for expanding the usable range of the lithium-ion battery and it has received intensive attention from numerous researchers. Solar cells can generate electricity from the sunlight and ensure sustainable access to electrical power for charging lithium-ion batteries. Herein, a photo-charging integrated device is constructed by combining four conventional dye-sensitized solar cells and a three-electrode hybrid lithium-ion battery, including a dye-sensitized TiO2 photo-anode, LiFePO4 electrode and metal lithium electrode. When the device is operated under solar illumination, DSSCs can match the charging voltage for the hybrid lithium-ion battery. The LiFePO4 electrode in the three-electrode device plays two roles, serving as a reversible redox agent for the regeneration of dye and as the cathode for lithium-ion batteries. The integrated device can effectively harvest solar energy and store it in situ within the hybrid lithium-ion battery through the photo-charging process. The proposed strategy is in favor of exploiting the small-sized, light-weight, self-chargeable battery and may have the potential to be employed as the power supply for miniaturized sensors and mobile devices.

Near-infrared (NIR)-persistent luminescence (PersL) materials are of promising applications in labeling, tracing, bio-imaging, and so forth, featuring distinctive self-sustained NIR light emitting. The PersL radiation spectrum, PersL duration, and charging efficiency are recognized as the key enablers for high-performance NIR PersL materials. Here, we have designed and developed a series of broad-band NIR superlong PersL phosphors (Sr,Ba) (Ga,In)12O19:Cr3+ with efficient UV-red light charging capacity. Typical SrGa10.49In1.5O19:0.01Cr3+ presents intensive NIR PersL from 650 to 1000 nm peaking at ∼770 nm, with a PersL duration of 360 h. This material can be efficiently and repeatedly charged by solar radiation in various outdoor environments. Our work further identifies that this NIR PersL material is advantageous for labeling and tracing as a secret NIR additive and in situ bio-imaging as an optical probe under high tissue penetration red light excitation.

UV-charged optical stimulated single-band phosphors are being used for single-level optical data storage because of their ability to easily write/read information by light. In contrast, UV–visible–NIR rechargeable optical stimulated double-band phosphor is urgently necessary for multiplexed high-throughput optical data storage. Here, the authors design and synthesize Mn 2+ ,Cr 3+ co-doped zinc gallate storage persistent phosphor that exhibits strong red-green bicolor persistent luminescence (PersL). Besides the traditional ultraviolet charging, the phosphor can be effectively and repeatedly charged by using visible and NIR light by one- or two-photon process. Interestingly, red and green PersL exhibit the opposite temperature dependence, which is extremely important for multilevel information storage. The mechanism of temperature-dependent PersL intensity based on different trap types and filling approaches for the double luminescence centers is proposed. The phosphor promises a sophisticated application in optical data storage of wavelength multiplexing.

A photorechargeable supercapacitor was constructed using vanadium pentoxide (V2O5), reduced graphene oxide hydrogel (rGH), and zinc trifluoromethanesulfonate (Zn(CF3SO3)2) as the photoanode, cathode, and electrolyte, respectively. The phase composition, microstructure, chemical structure, light absorption, and specific surface area of the synthesized products and the electrochemical performance of the rGH/V2O5 supercapacitor were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), Raman spectroscopy, UV-Vis spectroscopy, the Brunauer–Emmett–Teller (BET) method, and an electrochemical workstation, respectively. The results show that the device has a specific capacity of 164 F g−1 at 0.5 A g−1 under illumination with 95 mW cm−2 light intensity, which is 20.5% higher than that under normal electrical charging. The supercapacitor has a 75% capacity retention rate and 100% coulombic efficiency, respectively, after 10 000 testing cycles under photoelectric synergistic charging and discharging. The as-constructed rGH/V2O5 photorechargeable supercapacitor exhibits promising application potential in electric vehicles and wearable electronics.

Due to the depletion of fossil fuels, extensive CO 2 emissions, and growing demand for electrochemical energy, it is important to develop further utilization of renewable energy, as well as advanced energy storage techniques. To this end, the optically chargeable supercapacitor, which can convert the photon energy of solar light into electrochemical energy and store it for long-term usage, attracts extensive investigations. Among these, heterojunction construction was revealed as an effective method to enhance capacity. Recent works have reported the implementations of precipitation in ceramics, where the introduced matrix-precipitate two-phase structure is inspiring for constructing heterojunction, whereas it was seldom reported. In this work, Li-doped NaNbO 3 electrode material was prepared by adopting a multi-step solid reaction to precipitate LiNbO 3 and construct LiNbO 3 /NaNbO 3 heterojunctions. The electrochemical measurement demonstrates an enhanced optically chargeable capacity of roughly 85% increase at a scan rate of 1 mV/s and a four-fold increase at a charging–discharging current density of 1 A/g, as well as outstanding stability by introducing precipitates and constructing heterojunctions. This finding proposes a novel methodology design of heterojunction construction via precipitation to enhance the optically chargeable capacity of supercapacitor electrode materials and, therefore, may open up a potentially new application field for precipitate-tuned functionality in functional ceramics.

In tumor therapy, copper (Cu)-based nanozymes with peroxidase-like activity play a crucial role in converting hydrogen peroxide into hydroxyl radicals ( OH). This process induces immunogenic cell death, which in turn activates the body’s immune response, enhancing the efficacy of tumor immunotherapy. Nonetheless, the efficiency of this reaction is curtailed due to the oxidation of Cu(I) to Cu(II), leading to the self-depletion of the nanozyme’s activity and an insufficient yield of OH for effective immunotherapeutic activation. To surmount this challenge, our research introduces a photocharging self-doped semiconductor nanozyme, copper sulfide (Cu 9 S 8 ). The photocharging effect enables the nanozyme to convert internal Cu(II) back to Cu(I) through charge transfer induced by near-infrared (NIR)-II photothermal energy, thereby effectively maintaining the enzyme-like activity of the nanozyme. Additionally, Cu 9 S 8 is enhanced with a calcium sulfide (CaS) coating. This coating reacts in the acidic microenvironment of tumors to generate hydrogen sulfide (H 2 S) gas, which in turn suppresses the catalase activity inherent in tumor cells, ensuring a plentiful supply of H 2 O 2 for the nanozyme’s operation. This dual strategy of amplifying enzyme-like activity and substrate availability culminates in the generation of ample OH within tumor cells, leading to significant immunogenic cell death and thereby realizing potent immunotherapy.
