Abstract:
A method for forming a transparent conductive oxide (TCO) film for use in a TFPV solar device comprises the formation of a tin oxide film doped with between about 5 volume % and about 40 volume % antimony (ATO). Advantageously, the Sb concentration generally ranges from about 15 volume % to about 20 volume % and more advantageously, the Sb concentration is about 19 volume %. The ATO films exhibited almost no change in transmission characteristics between about 300 nm and about 1100 nm or resistivity after either a 15 hour exposure to water or an anneal in air for 8 minutes at 650 C, which indicated the excellent durability. Control sample of Al doped zinc oxide (AZO) exhibited degradation of resistivity for both a 15 hour exposure to water and an anneal in air for 8 minutes at 650 C.
