PURPOSE: To obtain a thin film solar cell having high conversion efficiency, without using harmful materials. CONSTITUTION: A thin film solar cell 1 has a structure comprising a metal back electrode 3, first p-type multi-element compd. semiconductor thin film 4 forming a photoabsorptive layer on the electrode layer 3, second n-type transparent and conductive metal oxide semiconductor thin film 6 forming a window layer, and third transparent high-resistance S-contained Zn mixed crystal compd. semiconductor thin film 5 laid at the interface between the films 4 and 5. The first semiconductor thin film 4 is grown on the layer 3, third semiconductor thin film 5 is chemically grown from a soln. on the film 4, and second semiconductor thin film 6 is grown on the film 5 to produce the cell 1. |
