CuGaInSe2/CdS thin film solar cell with an efficiency in excess of 15% have been prepared by a novel three stage selenization method. The first stage consists in the deposition of Cu, In Ga elemental layer on Mo covered soda lime glass and selenization of the layers in a Se vapour. For the second and third stage only Cu and Ga are used as elemental layers in order to increase the amount of Ga in CuGaInsSe2 film.

Abstract
CuGaInSe2/CdS thin film solar cell with an efficiency in excess of 15% have been prepared by a novel three stage selenization method. The first stage consists in the deposition of Cu, In Ga elemental layer on Mo covered soda lime glass and selenization of the layers in a Se vapour. For the second and third stage only Cu and Ga are used as elemental layers in order to increase the amount of Ga in CuGaInsSe2 film.
