Abstract

original image

A smart strategy to significantly improve the energy conversion efficiency of the wide-bandgap polymer P3HT blended in PCBM is demonstrated through NIR sensitization with a low-bandgap polymer. An efficiency of over 4% is achieved by adding 30–40% of the low bandgap polymer Si-PCPDTBT to the binary P3HT:PCBM blend, corresponding to an efficiency improvement of 25% compared to the P3HT:PCBM reference binary blend.
