Abstract

A dye sensitized solid-state solar cell (DSSC) was fabricated consisting of a dense TiO2 (D) and a nanoporous TiO2 (P) layers. The dense TiO2 layer of the DSSC type TiO2(D)/TiO2(P)/Dye/CuI prevents the short circuit problem, which normally encounter in DSSC while the poor dye adsorption of the dense TiO2 film is compensated using a porous TiO2 layer. The dense TiO2 film provides the opportunity of optimizing the performance of the second porous layer and the overall cell performance. i.e. TiO2(D)/Dye/CuI solar cell delivers Isc = 1.20 mA and Voc = 345 mV while solar cell consisting of a porous TiO2 layer on the dense TiO2 layer (TiO2(D)/TiO2(P)/Dye/CuI) delivers Isc = 6 mA and Voc = 500 mV.
