제목 New conjugated small-molecule dyes using the electron-withdrawing group of 2-(2-methyl-4H-chromen-4-ylidene)malononitrile and their application in photovoltaic devices
초록 In organic solar cells, we have synthesized new acceptor-donor-acceptor conjugatedsmall-molecule dyes derived from IDTT and CMCN. These are named IDTT-CMCN andIDTT-HT-CMCN. Small molecules with the A-D-A structure can effectively form apowerful push-pull structure, resulting in intramolecular charge transport(ICT) and enhanced optical absorption. To increase solubility and extend the π-conjugation length of IDTT-HT-CMCN, HT is used as a π-bridge unit between the IDTT and CMCN moieties. The PCE (7.60%) reportedin this work is among the highest reported values for an organic solar cellwith an IDTT-based small-molecule donor.
