The joining of Y6 has effectively promoted the power conversion efficiency (PCE) organic solar cells, and impact its end-group modification on PCE is significant. Here, eight different groups are introduced to modify Y6, forming acceptors named V1, V2, V3, V4, V5, V6, V7, R. excited states, light absorption properties, intermolecular electron transfer discussed by density functional theory. state, average local ionization energy, Hirshfeld population, potential, affinity, mobility also calculated. Results show that V7 obtains largest red-shift in UV-visible spectra (787.55 nm). V5 have better electronic coupling while exhibiting leading (0.9577 0.4383 cm2 V-1 s-1). Acceptors with rigid skeletons, good planarity, minimal steric hindrance, locally uniform ALIE distributions potential achieve higher mobility. These results indicate precise engineering can regulate acceptors, thereby increasing PCE.

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.

A crucial challenge in the development of semi‐transparent solar cells is to maintain a reasonable power conversion efficiency (PCE) while reaching high average visible transparency (AVT). Typically, organic semiconductors are favorable for this application since they can selectively absorb infrared light transmitting light. This ability stems from limited electronic states at high(er) energies contrast inorganic with their typical rise absorption coefficient toward higher photon energies. To increase PCE AVTs, series dielectric Bragg reflectors developed cells. Using multi‐layered back electrode (TiO 2 |SiN|TiO |AZO|Ag|AZO) PV‐X Plus as photoactive layer and metal‐free PEDOT:PSS top electrode, utilization (LUE = AVT × PCE) up 4.32% achieved, together an 47.9%. Although short circuit current agree well optical simulations, low fill factor (FF) partial shunting limit overall device performance. ZnO PFN‐Br additional electron transport layers modifying stack |SiO |TiO accordingly leads LUE 4.6% remarkable 51.9% maximum 8.79%.
