Abstract / Description of output

Recently, enormous research passion has been devoted to enhance the power conversion efficiency (PCE) of porphyrin sensitizers for DSSCs, but the major stumbling block is its absorption defects in visible spectrum region. To address the challenge, herein we reported a duplexing high performance photovoltaic result for DSSCs based on a novel D-π-A sensitizer FW-1 7H-Dibenzo[c,g] carbazole-substituted and fused Zn-porphyrin, co-sensitized with benzotriazole featured dye (WS-5) in iodine and cobalt redox system and got high PCE of 10.21% and 10.42%, respectively. An unprecedented breakthrough was got for supplying the gap of one sensitizer suitable for more electrolyte systems due to the appropriate molecular orbitals and co-sensitizer.
