Abstract

Recently, ternary semi-transparent organic photovoltaics (STOPVs) have developed rapidly due to their impressive application prospect in vegetable greenhouse, smart light window, and building-integrated solar cells. However, STOPVs have special requirements for the thickness of the active layer, which will affect the performance of the solar cells. Therefore, a new method developed to trade off device performance and average transmittance (AVT) are extremely important. Herein, we used an insulating polymer poly(N-vinylcarbazole) (PVK) as a color control agent to improve the AVT without changing the power conversion efficiency (PCE) of ternary STOPVs. Through mixing of PVK, the STOPVs show remarkable enhancement of the hole mobility and visible light transmittance, which leading the AVT of the device reaches 23.2% while maintaining the PCE over 14%. This method can effectively realize the preparation of high-performance neutral STOPVs, which is worthy of further promotion and research.
