Material Technology for Flexible Thin Film Dye-Sensitized Solar Cells

Abstract

Here, in this work, a 28 GHz microwave irradiation process for flexible dye-sensitized solar cells is newly proposed. The resulted cell performance improved by microwave heating from 0.45 % to 0.74 %at 2.45 GHz, and up to 2.16 % at 28 GHz. Relatively high open circuit voltage of 685 mV at 28 GHz irradiation is considered to the better electrical connectivity of each nano size TiO₂ particles. This well firing resulted higher photo-electron conversion efficiency.
