Interfacial Engineering for Organic Solar Cells

Abstract

Organic solar cells (OSCs) have been considered promising renewable energy source because of compatibility with flexi- ble, low weight, large area device application, low cost and solution processibility. Organic solar cells with bulk hetero- junction (BHJ) structure with polymer donor and fullerene acceptor have recently achieved power conversion efficiency of 10% and have potential application to commercial use. For realizing this goals, Interfacial engineering is required for ach- ieving
