Characteristics of Dye-Sensitized Solar Cells Using Various Dyes

Abstract

Dye-sensitized solar cells have been fabricated using dyes of ruthenium, NKX-2553, rosehip, blueberry, coffee, and hibiscus, and the characteristics of the dye-sensitized solar cells fabricated have been measured. As a result, it is found that the conversion efficiency of the dye-sensitized solar cell in which ruthenium-dye is used is about 8%, whereas those of the dye-sensitized solar cells in which dyes of rosehip, blueberry, coffee, and hibiscus are used are 0.023, 0.019, 0.015, and 0.015 %, respectively. We have also proposed the perfectly solid-state dye-sensitized solar cell using the poly(dimethyl silane) thin film which is fabricated by the vacuum evaporation technique.
