Abstract
Oxide coatings for solar cells deposited from organic solutions were studied. Among them, an Al203 layer was found to decrease the surface recombination velocity of a silicon wafer to about 1 /10 of its value with no coating. The new constitutions were designed by inserting a thin Al203 layer between the silicon substrate and the antireflective layers. IR absorptions and the capacitance-voltage characteristics indicated that the reduced surface recombination velocity corresponded to the decrease of the surface state den-sity by the terminating action of H or OH. Instead of TiO2, a Ta205 layer was introduced to improve the absorption of the short wavelength radiation. By inserting the thin Al203 layer, the efficiency of the solar cell increased by about 5%.
