文摘
Self-doped and crown-ether functionalized fullerene PCMI:K+ works well as a cathode buffer layer in polymer solar cells based on PTB7-Th, with a power conversion efficiency (PCE) of 10.30%, which is one of the highest PCEs to date. A series of experiments are used to shed light upon the mechanism of the simultaneous elevation in photovoltaic parameters with PCMI:K+.
