Organic solar cells based on small molecule donors and polymer acceptors operating at 150 °C

Abstract

Inorganic and organic solar cells always operate at a temperature lower than 100 °C and are not suitable for operating at high temperature. In this work, using blends of a small molecule donor and a polymer acceptor (MD/PA-type) as the active layers, we develop efficient and stable organic solar cells (OSCs), which can operate at a temperature of up to 150 °C. The device exhibits a power conversion efficiency (PCE) of 9.51%, which is the highest value reported to date for MD/PA-type OSCs. After thermal treatment at 150 °C for 72 hours, the device can retain 84% of its initial PCE value. This superior device stability at high temperature is attributed to the high phase transition temperatures of the two materials in the MD/PA-type active layer. This work suggests a new advantage of high-temperature tolerance for OSCs.
