Abstract
TiO2nanocrystalline semiconductor film was made on the titanium (Ti) substrate by hydrothermal method,and then prepared the CdSe quantum dot layer on the face of the TiO2nanocrystalline semiconductor film by electrochemical deposition method. We studied the affect of deposition voltage of the CdSe quantum dots’ growth, finding that when the deposition voltage was-1.3V,CdSe quantum dots grown best.However, In terms of CdSe/TiO2as the light-anode,using electricity chemistry workstation to test,We gain a solar cell with Short circuit current density of 1.45×10-3A·cm-2and the open circuit voltage of 0.24 V.
