High power conversion efficiency (PCE) and long-term stability are essential prerequisites
for the commercialization of polymer solar cells (PSCs). Small-molecule acceptors (SMAs) …

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 …

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 …

Precise design of fluorescent molecules with desired properties has enabled the rapid
development of many research fields. Among the different types of optically active materials …

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 …

Over the past few years, non‐fullerene organic solar cells have been a focus of research
and their power conversion efficiencies have been improved dramatically from about 6% to …

We design and synthesize four fused-ring electron acceptors based on 6, 6, 12, 12-tetrakis
(4-hexylphenyl)-indacenobis (dithieno [3, 2-b; 2′, 3′-d] thiophene) as the electron-rich unit …

In recent years, the development of non-fullerene acceptors (NFAs) has led to rapid
advances in organic solar cells (OSCs), resulting in power conversion efficiency (PCE) …

We report a novel small molecule acceptor (SMA) named FTTB-PDI4 obtained via ring-
fusion between the thiophene and perylene diimide (PDI) units of a PDI-tetramer with a …
