Mapping Polymer Donors toward High-Efficiency Fullerene Free Organic Solar Cells

Adv Mater. 2017 Jan;29(3). doi: 10.1002/adma.201604155. Epub 2016 Nov 10.

Abstract

Five polymer donors with distinct chemical structures and different electronic properties are surveyed in a planar and narrow-bandgap fused-ring electron acceptor (IDIC)-based organic solar cells, which exhibit power conversion efficiencies of up to 11%.

Keywords: fused ring electron acceptors; nonfullerene acceptors; organic solar cells; wide-bandgap polymer donors.
