    • Abstract

       

      CdSe films on titanium have been prepared by spray pyrolysis and characterized by X-ray diffraction and X-ray photon spectroscopy. Photoelectrochemical solar cells with 4·84% conversion efficiency have been fabricated using these electrodes. Spectral response studies indicate absorption at sub-band gap energies. The band gap of CdSe as determined from photo-current studies was 1·66 eV. The flat band potential measured gives a value of −1·54 V with reference to SCE for electrodes prepared using cadmium chloride and selenourea in the 1:1 ratio.
