Molecular Doping Enhances Photoconductivity in Polymer Bulk Heterojunction Solar Cells. (19th September 2013) - Zhang, Yuan
Abstract Addition of low concentrations (<1:100, dopant:donor) of a fluorinated p‐type dopant, F4‐TCNQ leads to a considerable enhancement of the photocurrent in PCDTBT:PC70BM bulk heterojunction solar cells. As a result, the power conversion efficiency increases from 6.41% to 7.94 %.
