Additive engineering for high-performance P3HT:non-fused ring electron acceptor organic solar cell

Abstract

In this study, we address the challenge of improving the power conversion efficiency (PCE) of P3HT-based organic solar cells (OSCs) by modulating the phase separation morphology. We synthesize a non-fused...

Non-fused ring electron acceptors with an ethynylene linker for non-halogenated solvent-processed organic solar cells

“…A 500 nm laser was first used to excite the blend films and study the electron transfer. 41,42 As shown in Fig. 4a and b, the negative signals in the range of 500-610 nm and 700-830 nm are assigned to the ground state bleaching (GSB) signals of J52 and acceptors, respectively.…”
