摘要：
Hybrid bulk heterojunction solar cells based on inorganic-nanowire (NW)/conjugated-polymer composites have been shown to achieve a power conversion efficiency (PCE) of 1-3 %, which is much lower than theoretically expected. This work addresses the short exciton diffusion lengths in common photoactive polymers with a new solar-cell design that has a PCE of 4.68 % (see scheme; ITO=indium tin oxide, G-PEDOT:PSS=glycerol-doped poly(3,4- ethylenedioxythiophene)-poly(styrenesulfonate); E=electropolymerized; a=amorphous). © 2013 WILEY-VCH Verlag GmbH & Co.
