“…In addition, several strategies have been used to enhance the PEC properties of semiconductors, which Similarly, several n-type (CdS, CdSe) [32,33] and p-type (CIS, CIGS) [34,35] chalcogenides, nitrides (TaN, GaN) [36,37], phosphides (InP) [38], and Cu 2 Os [39] have been explored for solar water splitting applications, owing this to their narrow bandgap that absorbs sufficient visible light and well-matched band edge positions concerning overall water splitting potential. However, these materials suffer from poor stability and thus require catalytic support, coatings for improved stability, and long-term operation [38][39][40][41][42][43]. On the other hand, several materials such as Si, CuO, GaAs, etc.…”

The development of a single junction photoelectrode material having specific properties is essential and challenging for the efficient application in solar water splitting for oxygen production and a high value-added product, hydrogen. Moreover, the present material solutions based on binary metal oxides offer limited catalytic activity and hydrogen production efficiency. Therefore, it is paramount to develop and exploit a unique range of materials derived from ternary metal oxides with specifically engineered properties to advance in photoelectrochemical (PEC) water splitting. Among the ternary oxides, copper vanadates offer promising characteristics, such as a narrow bandgap and catalytic surface properties along with favorable band edges for facile oxygen evolution reaction (OER), which is considered the bottleneck step in performing overall water dissociation. Furthermore, the copper vanadates allow the tuning of the stoichiometry through which a wide range of polymorphs and materials could be obtained. This review provides a complete outlook on the range of copper vanadates and the established synthesis approach, morphology, crystal structure, band edge properties, and PEC characterizations. Mainly, the underlying charge dynamic properties, carrier path length, effect of doping, and influence of surface catalysts are discussed. The review concludes that the advancement toward obtaining low-bandgap materials is a main challenge to overcome the limitations for efficient water dissociation to OER and copper vanadates, which offer a promising solution with their unique properties and advantages. Importantly, intense and strategically focused research is vital to overcome the scientific challenges involved in copper vanadates and to explore and exploit new polymorphs to set new efficiency benchmarks and PEC water splitting solutions.

“…Aoki RM et al [9] prepared CdS and CdS/ZnS QDs using a hot injection method, which were used as a luminescence downshifting (LDS) layer to improve the performance of the devices. Du et al [11] synthesized CdTe/CdSe composite QDs in an aqueous solution in one step method and prepared polyvinyl alcohol (PVA)/QDs films by spincoating to achieve efficiency gains of up to 26.83%. However, traditional cadmium-based QDs preparation requires hightemperature synthesis [12], which is high-cost and complicated, and is not suitable for large-scale manufacturing.…”

Silicon solar cell is the most mature photovoltaic conversion device, and in order to further improve the performance of the device, application of downshifting films has become a research hotspot. In this paper, CsPbBr3 perovskite quantum dot/EVA composite adhesive film was prepared by melting method with CsPbBr3 perovskite quantum dot film under solution processing as masterbatch and EVA particles as excipient. The effect of synthesis conditions on the luminescence properties of the composite films were thoroughly studied. The optimized CsPbBr3 perovskite quantum dot/EVA composite adhesive film has excellent performance, and its light transmission reaches 85%. The CsPbBr3 perovskite quantum dot/EVA composite adhesive film absolutely improves the efficiency of silicon solar cells by 1.08%, which is much higher than that of pure EVA adhesive film (0.63%). In addition, the device efficiencies have almost no change after 30 days in the air, maintaining the working stability of the device and contributing to industrial applications. This study provides a novel, industrial and low-cost synthesis route for the synthesis of CsPbBr3 perovskite quantum dot/EVA composite adhesive film, which is expected to have broad application.
