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 …

The bulk-heterojunction blend of an electron donor and an electron acceptor material is the
key component in a solution-processed organic photovoltaic device. In the past decades, a p …

Over the past three years, a particularly exciting and active area of research within the field
of organic photovoltaics has been the use of non-fullerene acceptors (NFAs). Compared …

Non-fullerene acceptors (NFAs) are currently a major focus of research in the development
of bulk-heterojunction organic solar cells (OSCs). In contrast to the widely used fullerene …

The field of non-fullerene organic solar cells has experienced rapid development during the
past few years, mainly driven by the development of novel non-fullerene acceptors and …

Fullerenes have formed an integral part of high performance organic solar cells over the last
20 years, however their inherent limitations in terms of synthetic flexibility, cost and stability …

The ternary strategy has been identified as a feasible and effective way to obtain high-
efficiency organic solar cells (OSCs). However, for most ternary OSCs, the voltage loss …

Abstract 3, 4, 9, 10‐Perylenetetracarboxylic dianhydride (PDI) is one of the best n‐type
organic semiconductors and an ideal light‐driven catalyst for lignin depolymerization …

Morphology control greatly influences the power conversion efficiency (PCE) and long‐term
stability of all‐polymer solar cells (all‐PSCs); however, it remains challenging owing to their …

A nonfullerene-based polymer solar cell (PSC) that significantly outperforms fullerene-based
PSCs with respect to the power-conversion efficiency is demonstrated for the first time. An …
