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.

Abstract Semitransparent organic photovoltaics (ST‐OPVs) hold great promise for building‐integrated applications but encounter a critical trade‐off between power conversion efficiency (PCE) and visible transparency. This work addresses this challenge by introducing novel theoretical framework that synergistically combines optical modeling material design. A piecewise Gaussian absorption model has been developed to accurately simulate asymmetric spectral characteristics of materials. enables the virtual screening potential donor‐acceptor configurations, identifying two optimal configurations: narrow‐narrow (N + N) system wide‐narrow (W system, which achieve superior balance PCE High‐throughput bilayer coupling layers further enhances light utilization 9.8% 9.3% through optimized management. study bridges properties engineering, providing predictive tool ST‐OPV optimization guide development high‐performance, visually transparent solar technologies.
