About High electron donor polymers photovoltaics

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 and electron–donor materials.

Solar cells are an important renewable energy technology owing to the abundant, clean.

Historically, fullerene derivatives such as [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) have been the most used acceptors in OSCs. The BHJ concept was introduced.

To overcome the limitations of fullerene acceptors, non-fullerene SMAs are being explored as possible replacements. The development of SMAs for OSCs has also been facilit.

All-polymer solar cells (all-PSCs) are OSCs in which both the donor and acceptor components are polymers. In one of the first examples of BHJ OSCs, reported in 1995, two p.

The main reason to develop all-small-molecule OSCs (all-SMOSCs) is to avoid the batch-to-batch reproducibility problem of polymers160. By comparison, small-molecule m.
