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.
