Abstract Organic solar cells (OSCs) have been developed for few decades since the preparation of first photovoltaic device, and record power conversion efficiency (PCE) certified by national renewable energy laboratory (NREL) has exceeded 17%. Looking back whole history OSCs, its rapid development is inseparable from multi‐disciplinary efforts, including new materials synthesizing, device physics, engineering, especially breakthroughs in these disciplines. In this review, we are aiming at reviewing OSCs summarizing representative breakthroughs.

Organic photovoltaics (OPVs) have developed rapidly since the advent of fused-ring electron acceptors (FREAs). FREAs bearing bulky cores, end-capped with electron-withdrawing groups, present advantages such as broad absorption, tunable frontier orbital levels, and good thermal stability. Recent breakthroughs demonstrate that FREA-based OPVs achieved more than 17% efficiency, among which end groups (EGs) 1,1-dicyanomethylene-3-indanone (IC) derivatives are critical for performance enhancement. To date, 50 IC been reported to construct high-performance OPVs. In this review, we first introduce chemical structure synthesis route group. We discuss classify recent progress based on its derivatives, well impact morphology. consider issues EGs face, including stability, isomerism, EG redistribution, finally proposing some future directions derivatives.

Small-molecule acceptor (SMA)-based organic solar cells (OSCs) have achieved high power conversion efficiencies (PCEs), while their long-term stabilities remain to be improved meet the requirements for real applications. Herein, we demonstrate use of donor-acceptor alternating copolymer-type compatibilizers (DACCs) in high-performance SMA-based OSCs, enhancing PCE, thermal stability, and mechanical robustness simultaneously. Detailed experimental computational studies reveal that addition DACCs polymer donor (PD)-SMA blends effectively reduces PD-SMA interfacial tensions stabilizes interfaces, preventing coalescence phase-separated domains. As a result, desired morphologies with exceptional stability are obtained blends. The 20 wt % affords OSCs PCE 17.1% cohesive fracture energy (Gc) 0.89 J m-2, higher than those (PCE = 13.6% Gc 0.35 m-2) control without DACCs. Moreover, at an elevated temperature 120 °C, DACC exhibit excellent morphological retaining over 95% initial after 300 h. In contrast, rapidly degraded below 60% 144
