摘要

Organic solar cells (OSCs) have experienced remarkable performance progress up to 20% benchmark power conversion efficiency (PCE) in past years. Considering the <1% initial PCE obtained by OSC decades ago, the milestone of surpassing 20% efficiency is of great significance. Meanwhile, further performance promotion is urgently required for OSCs as other solution-processable photovoltaic technologies are also competitive. This review article aims to demonstrate a comprehensive summary of recent reports on OSCs with over 20% PCE, delving into key strategies including material innovations, multi-component system construction, deposition protocol optimization, solid/solvent additive engineering, as well as hole/electron transport layer development. In addition, this study identifies the next-stage scientific and technological issues that warrant greater attention. These issues are proposed to drive more prosperous research development, particularly in the field of flexible and wearable power suppliers.
