Abstract Although organic solar cells have surpassed 20% power conversion efficiency, a persistent trade-off between open-circuit voltage and fill factor (FF) prevents them from closing the gap with inorganic technologies. Here we investigate this trade-off across a wide range of devices and identify an FF limit arising from field-dependent free-charge generation. This limit becomes more severe as voltage losses are minimized, thereby imposing an open-circuit voltage–FF trade-off.

Abstract In the pursuit of advancing the commercialization of organic solar cells (OSCs), stability emerges as a paramount challenge. Herein, we show that the electron transport connectivity is a key factor determining the electron transport and device stability of OSCs. When compared to small molecular acceptors (SMAs), the larger-size polymeric acceptors (PAs) are likely to establish an electron transport network with superior connectivity.

Regulating Crystallinity of Dimeric Acceptors via Central Core Engineering for Efficient Ternary Organic Solar Cells Controlling the crystallization behavior of the active layer is essential for optimizing the photovoltaic performance of ternary organic solar cells (TOSCs). Precisely tuning crystallinity is a key strategy to improve power conversion efficiency (PCE).
