A thin-film solar cell that can improve conversion efficiency while using an inexpensive raw material has been desired. A thin film solar cell according to the present invention includes one or more organic semiconductors and a coordination polymer, and the coordination polymer is one or two selected from transition metal elements. Containing a repeating unit of a complex in which a ligand composed of one or more sulfur-containing compounds, nitrogen-containing compounds, oxygen-containing compounds, and phosphorus-containing compounds capable of coordinating to the metal ions is coordinated to the above metal ions It is a thing to do.
