Abstract
Oxide coatings for solar cells deposited from organic solutions were studied. Among them, Al203 layer was found to decrease the surface recombination velocity of silicon by about one tenth. Thus new constitution was designed by inserting thin Al203 film between silicon substrate and AR coating. IR absorption and C-V characteristics indicated that the reduced surface recombination velocity corresponded to the decrease of surface state density by terminating action of H or OH. Instead of Ti02, Ta205 layer was introduced to improve the absorption of short wavelength. As the effect of Al2O3 layer the efficiency increased by about 5 %.
