Abstract
Bulk-heterojunction (BHJ) solar cells based on phase-separated blends of organic materials of donor and acceptor (fullerene derivative) have been in continuous development over the past two decades. [ 1-8 ] Recently, solution-processable small moleculebased BHJ solar cells exhibiting comparable power conversion effi ciency of near 8% to the polymers with high potential under simple and optimized processing conditions. [ 9-13 ] The smallmolecule donors have attractive features, including relatively simple synthesis and purifi cation steps, mono-dispersity, and improved batch-to-batch reproducibility.
