THIN FILM SOLAR CELL AND MANUFACTURING METHOD THEREFOR

摘要

In the present invention, in order to achieve a point contact, a thin film solar cell has a thin film light absorbing layer (3) disposed between a transparent conducive film (4) and a back-side metal electrode layer (2), and at the interface between the back-side metal electrode layer (2) and the light absorbing layer (3), the thin film solar cell is provided with a nanoparticle dispersion layer (5) including nanoparticles (6, 6 . . . ), where at least the surface of the nanoparticles is an insulator.
