Show more >Multifunctional semitransparent organic photovoltaics (ST-OPVs) combining power generation, light transparency, and heat rejection have emerged as a promising technology for application in building-integrated photovoltaic systems, but maximizing all of these features simultaneously is challenging. Herein, we show that high-throughput optical screening is essential to guide the design of infrared reflectors and enhance their synergy with organic absorbers. Taking advantage of a volatile additive, 1,3,5-trichlorobenzene, to improve the crystallinity of the binary PM6:L8-BO active layer, we developed an optimized infrared reflector, consisting of a Na3AlF6 (160 nm)/ZnSe (190 nm) bilayer, which concomitantly increases all of the key parameters of the reflector-free device. High-performance multifunctional ST-OPVs with a power conversion efficiency of 15.19%, an average photopic transmittance of 30.57%, a color rendering index of 81.86, and an infrared rejecting rate over 90% are demonstrated, providing practical prospects for future sustainable building-integrated photovoltaic systems.Show less >
