Perovskite solar cells (PSCs) have made incredibly fast progress in the past years, with the
efficiency approaching 26%, which is comparable to those of the best silicon solar cells. One …

Morphology optimization is critical for achieving high efficiency and stable bulk‐
heterojunction (BHJ) organic solar cells (OSCs). Herein, the use of 3, 5 …

Given that bromine possesses similar properties but extra merits of easily synthesizing and
polarizing comparing to homomorphic fluorine and chlorine, it is quite surprising very rare …

The ternary strategy has been widely identified as an effective approach to obtain high‐
efficiency organic solar cells (OSCs). However, for most ternary OSCs, the nonradiative …

The π‐expansion of non‐fullerene acceptors is a promising method for boosting the organic

The performance of organic solar cells (OSCs) has increased substantially over the past 10
years, owing to the development of various high-performance organic electron–acceptor …

Fused-ring electron acceptors (FREAs) have a donor–acceptor–donor structure comprising
an electron-donating fused-ring core, electron-accepting end groups, π-bridges and side …

Balancing and improving the open‐circuit voltage (Voc) and short‐circuit current density
(Jsc) synergistically has always been the critical point for organic photovoltaics (OPVs) to …

The nonradiative energy loss (∆ E nr) is a critical factor to limit the efficiency of organic solar
cells. Generally, strong electron-phonon coupling induced by molecular motion generates …
