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

During the past 30 years of research in organic electronics, the development of mechanistic
understanding of important structure–processing–performance interrelationships has been …

Rapid increase in the power conversion efficiency of organic solar cells (OSCs) has been
achieved with the development of non-fullerene small-molecule acceptors (NF-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 …

Organic semiconductors require an energetic offset in order to photogenerate free charge
carriers efficiently, owing to their inability to effectively screen charges. This is vitally …

Although the field of polymer solar cell has seen much progress in device performance in
the past few years, several limitations are holding back its further development. For instance …

The status of understanding of the operation of bulk heterojunction (BHJ) solar cells is
reviewed. Because the carrier photoexcitation recombination lengths are typically 10 nm in …

The optoelectronic properties of macromolecular semiconductors depend fundamentally on
their solid-state microstructure. For example, the molecular-weight distribution influences …

Organic semiconductors offer the potential for large-area deposition on substrates of flexible
or unique form factors and can be deposited at ambient conditions at low cost. They can be …
