Large area organic photovoltaic modules fabricated on a 30 cm by 20 cm substrate with a power conversion efficiency of 9.5%

The performance of OPV module is strongly dominated by the innovating materials and state of the art processes. Herein, we present a large-area and solution-processable OPV module, which the non-fullerene based active layer and interlayers are all deposited by blade coating. The module achieved a power conversion efficiency of 9.5% under 100 mW/cm² AM1.5G irradiation with an active area of 216 cm² on a 30 cm by 20 cm substrate. The power output can still maintain about 92.5% of the initial performance after 610 h of light soaking under 10000 lux LED irradiation. To the best of knowledge, it is the record high efficiency by far for OPV module with an active area over a hundred square centimeters.
