Single-component organic solar cells with over 11% efficiency

Abstract

Achieving stable high-efficiency single-component devices is a challenging problem in the field of organic photovoltaics. Recently in Joule, Min and co-workers reported a single-component organic solar cell using a conjugated donor-acceptor block copolymer (PBDB-T-b-PYT); a remarkable efficiency of 11.32% was realized with impressive photostability and storage stability.
