Abstract

A dye-sensitized solar cell was assembled by adsorbing dye onto TiO2 porous film, deposited on TCO glass. Photovoltage of DSSC under chopped light was studied and compared to a standard silicon cell. It was observed that DSSC has a slower response to pulsed irradiation than crystalline silicon cells. The influence of hydrochloric acid as electrolyte additive on the response time and cell performance was investigated. It was found that, by adding HCl in the electrolyte, the cell efficiency is maintained and the response time decreases significantly. If HCl exceeds a limit value, response time becomes better, but efficiency decreases strongly..
