PROBLEM TO BE SOLVED: To provide an organic thin film solar battery having high conversion efficiency with a high yield.SOLUTION: In an organic thin film solar battery cell, when letting n be an integer of 2 or greater and k be an integer of 1 or greater and n or smaller, a k-th photoelectric conversion unit, having a k-th organic layer disposed between a k-th transparent electrode layer and a k-th metallic layer, is juxtaposed on a plane with a (k+1)-th photoelectric conversion unit having a (k+1)-th organic layer disposed between a (k+1)-th transparent electrode layer and a (k+1)-th metallic layer. The k-th metallic layer is electrically connected to the (k+1)-th transparent electrode layer, and the n transparent electrode layers respectively include tapers of an acute angle at electrode end portions, along the direction of the organic layer. |
