Photocurrent Enhanced by Singlet Fission in a Dye-Sensitized Solar Cell
Original language description
Investigations of singlet fission have accelerated recently because of its potential utility in solar photoconversion, although only a few reports definitively identify the role of singlet fission in a complete solar cell. Evidence of the influence of singlet fission in a dye-sensitized solar cell using 1,3-diphenylisobenzofuran (DPIBF, 1) as the sensitizer is reported here. Self-assembly of the blue-absorbing 1 with co-adsorbed oxidation products on mesoporous TiO2 yields a cell with a peak internal quantum efficiency of similar to 70% and a power conversion efficiency of similar to 1.1%. Introducing a ZrO2 spacer layer of thickness varying from 2 to 20 angstrom modulates the short-circuit photocurrent such that it is initially reduced as thickness increases but 1 with 1015 angstrom of added ZrO2. This rise can be explained as being due to a reduced rate of injection of electrons from the S1 state of 1 such that singlet fission, known to occur with a 30 ps time constant in polycrystal
