High‐Performance Organic Photovoltaics Incorporating Bulk Heterojunction and p–i–n Active Layer Structures

Abstract

Organic Photovoltaics Bulk heterojunction active layers (left) in organic photovoltaics comprise random nanoscale p-, n-type and mixed domains, providing efficient excitons dissociations but encountering recombination of transported electrons and holes. While p-i-n active layers (right) consist of mixed (i) layers surrounded by the p- and n-layers, perpendicular to the device plane, creating direct pathways for efficient charge transport after dissociation.
