New Phase for Organic Solar Cell Research: Emergence of Y-Series Electron Acceptors and Their Perspectives
State Key Laboratory of Silicon Materials · Zhejiang University
Abstract
With the recent emergence of a new class of high-performance nonfullerene acceptors (NFAs), organic solar cells (OSCs) have entered a new phase of research featuring high power conversion efficiencies (PCEs). In this Perspective, we summarize the recent progress made from Y-series NFAs and the matched polymer donors and analyze the molecular design strategies for boosting device performance. We also perform a PCE prediction of OSCs and propose requirements for NFAs, aiming at a PCE of 20%, which is comparable to those of Si and perovskite-based counterparts. Finally, we assess three factors of efficiency, stability, and cost and outline the challenges facing OSCs and the future development directions of OSCs.…
