Studies on the preparation and characterization of cdte thin films doped with 005 to 025 of sb zn and ag using stacked elemental layer method

Abstract

A major opportunity for the growth of polycrystalline thinfilmbased newlinePV industry is due to the shortage and increased cost of PVgrade single newlinecrystal silicon Sifeed stock which has traditionally depended heavily on newlinereject or waste Si from the semiconductor industry Among available thinfilm newlinesolar cells such as aSi CuInGaSe2 and CdTe materials cadmium newlinetelluride CdTe may be the strongest candidate for high throughput largescale newlinemanufacturing of polycrystalline thinfilm solar cells Because of its newlinehigh absorption coefficient 1X104 cm1 and direct bandgap 15 eV newlineabout 1 and#956;m thick CdTe film is enough for the absorption of 90 of photons newlinewith energy higher than its band gap newline newline
