High-efficiency CuIn[sub [ital x]]Ga[sub 1[minus][ital x]]Se[sub 2] solar cells made from (In[sub [ital x]],Ga[sub 1[minus][ital x]])[sub 2]Se[sub 3] precursor films

In, Ga, and Se were coevaporated to form precursor films of (In[sub [ital x]],Ga[sub 1[minus][ital x]])[sub 2]Se[sub 3]. The precursors were then converted to CuIn[sub [ital x]]Ga[sub 1[minus][ital x]]Se[sub 2] by exposure to a flux of Cu and Se. The final films were smooth, with tightly packed grains, and had a graded Ga content as a function of film depth. Photovoltaic devices made from these films showed good tolerance in device efficiency to variations in film composition. A device made from these films resulted in the highest total-area efficiency measured for any non-single-crystal, thin-film solar cell, at 15.9%.
