Abstract
In the present invention, in order to achieve a point contact, a thin film solar cell has a thin film light absorbing layer () disposed between a transparent conducive film () and a back-side metal electrode layer (), and at the interface between the back-side metal electrode layer () and the light absorbing layer (), the thin film solar cell is provided with a nanoparticle dispersion layer () including nanoparticles (), where at least the surface of the nanoparticles is an insulator.
