METHOD FOR MANUFACTURING COMPOUND THIN-FILM SOLAR CELL

摘要

A method for manufacturing a compound thin-film solar cell in which an n-type buffer layer for heterojunction is formed on a light-absorbing layer made of a p-type compound semiconductor and formed on a back electrode. A powder of an S compound containing an n-type dopant element is scattered over the light-absorbing layer or a solution into which an S compound containing an n-type dopant element is dissolved is applied over the light-absorbing layer. By heating and melting it, a buffer layer is formed. Thus, an n-type buffer layer for heterojunction having a good adhesion and stable characteristics is formed on a light-absorbing layer of a p-type compound semiconductor.
