Translucent film solar cells have significant applications in various scenarios, indicating strong potential for application. However, translucent typically only regulate the transmitted light intensity and cannot flexibly adjust transmission wavelength. Here, a perovskite nanowire (PNW) cell that utilizes capture performance of single to achieve flexible wavelength adjustment visible range was designed. The characteristic scale PNW enables absorption coefficients (Qabs) at different wavelengths, combined with constraint relationship among reflectivity, absorptivity, transmissivity, transmittance spectrum cell. In addition, effect increases open circuit voltage (VOC) by about 5%. Finally, can vary yellow, red, purple, highest PCE be maintained around 20%, which enhances application transparent cells.

The development of excellent electron transport layers (ETLs) is crucial for high-performance organic solar cells (OSCs). In this work, we have developed a novel, versatile ETL composed zinc oxide (ZnO) and fluorescent agent to enhance the photovoltaic performance photostability OSCs. Unlike bulk doping ZnO interlayer, use conjugated small-molecule agent, sodium 2,2'-([1,1'-biphenyl]-4,4'-diyldivinylene)-bis(benzenesulfonate) (CBS), modify surface thus construct ZnO/CBS bilayer structure. shows lower work function, which beneficial extraction. Moreover, photoinduced transfer from CBS increases conductivity ZnO. Notably, fluorescence generated by can also be quenched active layer, indicating existence exciton or charge between layer. bidirectional layer synergistically improves enhances performance. Consequently, PM6:eC9 PM6:L8-BO based OSCs with as achieve power conversion efficiencies 17.42 18.16%, respectively, are among highest levels in inverted thickness insensitivity PM6:eC9-based still exhibit high PCE 15.66% at thick-film 130 nm 20 CBS. addition, modification efficiently blocks ultraviolet light reduces catalytic activity thereby enhancing

Abstract Semi‐transparent organic solar cells (ST‐OSCs), designed to selectively absorb UV and NIR light while transmitting visible wavelengths, are highly promising for windows building‐integrated photovoltaics. However, simultaneously achieving high efficiency, transparency, scalability remains a significant challenge. In this work, green‐solvent‐processed, large‐area modules with optimized performance uniformity is demonstrated. By integrating strategies reduce non‐radiative recombination losses, cost‐effective double‐layered nanophotonic structure, high‐quality 12‐nm‐thin Ag top electrode, semi‐transparent devices achieved power conversion efficiency of 10.2% an average transmittance 42%, yielding utilization 4.2%. Scaling 5 × cm 2 modules, laser scribing, dead zones, geometric fill factor 96.1%, optimized. The opaque reach active‐area 13.0%, the achieve 9.4% AVT > 40%, demonstrate excellent reproducibility. This work provides scalable sustainable pathway ST‐OSC commercialization contributes next‐generation renewable energy solutions.
