Abstract

In this study, cadmium sulfide (CdS)-sensitized and Ruthenium (Ru)-dye (N3) sensitized solar cells have been fabricated and compared, where nanoporous titanium oxide (TiO₂) photoelectrode of equal thickness has been prepared on SnO₂:F coated glass substrate using TiO₂ paste. The CdS have been deposited by an ammonia free chemical bath deposition technique. The CdS-sensitized TiO₂ photoelectrodes show polycrystalline nature. The optical measurement reveals that absorbance edge of the CdS-sensitized TiO₂ photoelectrode extends up to 540 nm. The CdS solar cell shows moderate solar cell efficiency which is comparable with the Ru-based dye sensitized solar cell of this investigation.
