Study on photo-degradation of inverted organic solar cells caused by generation of potential barrier between PEDOT:PSS and PBDB-Ts

Abstract

We investigated the photo-stability of PBDB-T, which is a widely used donor material for state-of-the-art organic solar cells (OSCs), in OSCs. PBDB-T did not decompose upon 100 h of photo-irradiation in OSCs, however, we found that PBDB-T can dedope PEDOT:PSS which is a standard solution-processable hole transport material. The dedoped PEDOT:PSS can work as a barrier to the carrier transfer. This result could be important for development of stable high-performance OSCs and interface chemistry of organic devices.
