METHOD FABRICATING QUANTUM DOT-SENSITIZED PHOTOVOLTAIC CELL

摘要

PURPOSE: A method fabricating quantum dot-sensitized photovoltaic cell is provided to constitute the TiO2 nanoparticle in the TiCl4 solution. CONSTITUTION: The porosity titanium dioxide(TiO2) layer is formed in upper part of the transparent conductive substrate. The quantum dot CdS is formed by the spray-pyrolysis of the precursor solution to the porosity titanium dioxide(TiO2) layer. After dipping the substrate having the quantum dot CdS in the TiSl4TiCl4 solution, the photo anode is formed by heat-treatment. After the cathode is positioned in order to put opposite to photocathode, electrolyte is the hermetic sealing. The thermal process operates in 400°C to 450°C. The precursor solution contains the sulfur precursor of the cadmium precursor of 0.001M to 0.5M and 0.001M to 0.5M.
