Organic solar cells are composed of electron donating and accepting organic
semiconductors. Whilst a significant palette of donors has been developed over three …

With the development of non-fullerene acceptors (NFAs), the power conversion efficiency
(PCE) of organic solar cells (OSCs) has been continuously improved and has exceeded …

Emerging nonfullerene acceptors (NFAs) with crystalline domains enable high-performance
bulk heterojunction (BHJ) solar cells. Thermal annealing is known to enhance the BHJ …

A series of tetrathiophene‐based fully non‐fused ring acceptors (4T‐1, 4T‐2, 4T‐3, and 4T‐
4), which can be paired with the star donor polymer PBDB‐T to fabricate highly efficient …

The high voltage losses (V loss), originating from inevitable electron-phonon coupling in
organic materials, limit the power conversion efficiency of organic solar cells to lower values …

Organic solar cells benefit from non‐fullerene acceptors (NFA) due to their high absorption
coefficients, tunable frontier energy levels, and optical gaps, as well as their relatively high …

Inhibiting excessive aggregation and migration of active layer molecules is essential to
improve the stability and performance of organic solar cells (OSCs). Herein, the star-shaped …

Hybrid perovskite solar cells have been creating considerable excitement in the photovoltaic
community. However, they still rely on toxic elements, which impose severe limits on their …

Comprehensive Summary By simplifying the π‐bridge unit, a nonfused ring electron
acceptor (NFREA) BM‐2F was designed and synthesized with several high‐yield steps. The …

Solar energy is free from noise and environmental pollution. It could be used to replace non-
renewable sources such as fossil fuels, which are in limited supply and have negative …
