INK FOR PRODUCTION OF COMPOUND SEMICONDUCTOR THIN FILM, COMPOUND SEMICONDUCTOR THIN FILM PRODUCED USING THE INK, SOLAR CELL EQUIPPED WITH THE COMPOUND SEMICONDUCTOR THIN FILM, AND PROCESS FOR PRODUCTION OF THE SOLAR CELL

摘要

An ink for forming a compound semiconductor thin film is provided, which comprises a binder comprising a compound comprising an S atom or an Se atom and metallic compound particles which are both dispersed in an organic solvent. A compound semiconductor thin film is formed by applying or printing the ink for forming a compound semiconductor thin film and heat-treating it. A solar cell is constituted, which has a light-absorbing layer formed of the compound semiconductor thin film.
