25_23b/2013Polymer Solar Cells: Efficient Small Bandgap Polymer Solar Cells with High Fill Factors for 300 nm Thick Films (Adv. Mater. 23/2013)

The morphology of a new high molecular weight push-pull semiconducting donor polymer provides a semi-crystalline fibrous network of polymers chains when blended with a fullerene acceptor. This organized morphology enables reaching high fill factors and power conversion efficiencies in organic solar cell for films up to 300 nm thickness, as reported by René A. J. Janssen and co-workers on page 3182. Image: ICMS Animation Studio, TU/e.
