ResumoThe electrodeposition of CdSe crystals has been examined under potentiostatic condition on graphite electrodes in LiClKCl melts containing CdCl2 and Na2SeO3. Deposits with various morphologies, needle-like, hollow-like, dendritic and columnar crystals, have been obtained by controlling the deposition potential. These as-grown deposits have fairly good photoelectrochemical characteristics and photoelectrochemical cells with a maximum conversion efficiency of 6.1% under white light illumination of 37 mW/cm2 were constructed using a CdSe photoanode.
