title: Mapping Polymer Donors toward High-Efficiency Fullerene Free Organic Solar Cells.
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%.
