Abstract
Thin films of CuInSe2 were deposited on soda lime glass and Coming 7059 glass with and without Mo coating by the pulsed laser deposition method from a uniaxially hot pressed CuInSe2 target. Numerous deposition parameters were varied and resulting films were characterized by SEM, EDX and XRPD. All films deposited from a stoichiometric target are Se deficient. Post deposition selenization process or in situ Se excess lead to single phase CuInSe2 thin films. CuInSe2/CdS/ZnO heterojunctions prepared from the deposited layers reach photovoltaic conversion efficiencies of about 8.5%
