An enhancement of photo-performance of dye sensitized solid-state cell by avoiding formation of dye aggregates

Aggregation of indoline dye molecules was found to be decreasing performance of dye-sensitized solar cells. The effect of spacers which minimize formation of aggregates on the sensitization process of TiO2|dye|CuI solar cell was examined. Maximum power conversion efficiency of 3.6% and photovoltage of 580 mV were observed for D149 and D205 sensitized TiO2|dye|CuI solar cells, respectively.
