Published: Jan. 30, 2024

Abstract Semi‐transparent organic solar cells (ST‐OSCs) possess significant potential for applications in vehicles and buildings due to their distinctive visual transparency. Conventional device engineering strategies are typically used optimize photon selection utilization at the expense of power conversion efficiency (PCE); moreover, fixed spectral range always imposes an unsatisfactory upper limit its light (LUE). Herein, a novel solid additive named 1,3‐diphenoxybenzene (DB) is employed dual‐regulate donor/acceptor molecular aggregation crystallinity, which effectively broadens response ST‐OSCs near‐infrared region. Besides, more visible allowed pass through devices, enables satisfactory photocurrent high average transmittance (AVT) simultaneously. Consequently, optimal ST‐OSC based on PP2+DB/BTP‐eC9+DB achieves superior LUE 4.77%, representing highest value within AVT 40–50%, also correlates with formation multi‐scale phase‐separated morphology. Such results indicate that can simultaneously meet requirements minimum commercial plant photosynthesis when integrated roofs agricultural greenhouses. This work emphasizes significance additives tune ST‐OSCs, charts way photovoltaics economically sustainable development.
