摘要

All polymer solar cells (all-PSCs) possess the advantages of mechanical flexibility and morphology stability. In this review, we introduce the development history of the,n,-type conjugated polymer (,n,-CP), especially the recent research progress of the polymerized small molecule acceptors. In addition, the challenges and prospects of the,n,-CP and all-PSCs are analyzed and discussed.

Abstract

The active layer of all polymer solar cells (all-PSCs) is composed of a blend of a,p,-type conjugated polymer (,p,-CP) as donor and an,n,-type conjugated polymer (,n,-CP) as acceptor. All-PSCs possess the advantages of light weight, thin active layer, mechanical flexibility, low cost solution processing and high stability, but the power conversion efficiency (PCE) of the all-PSCs was limited by the poor photovoltaic performance of the,n,-CP acceptors before 2016. Since the report of the strategy of polymerized small molecule acceptors (PSMAs) in 2017, the photovoltaic performance of the PSMA-based,n,-CPs improved rapidly, benefitted from the development of the A-DA’D-A type small molecule acceptors (SMAs). PCE of the all-PSCs based on the PSMA acceptors reached 17%−18% recently. In this review article, we will introduce the development history of the,n,-CPs, especially the recent research progress of the PSMAs. Particularly, the structure-property relationship of the PSMAs is introduced and discussed. Finally, current challenges and prospects of the,n,-CP acceptors are analyzed and discussed.
