N-TYPE DIFFUSION LAYER FORMING COMPOSITION, METHOD OF PRODUCING N-TYPE DIFFUSION LAYER, AND METHOD OF PRODUCING SOLAR CELL ELEMENT

摘要

The disclosed n-type diffusion layer forming composition is constituted so as to contain a glass powder containing a donor element and having a softening temperature of 300-950C, and a dispersion medium. By applying a coating of said n-type diffusion layer forming composition and performing thermal diffusion treatment, an n-type diffusion layer, and a solar cell element having the n-type diffusion layer, are produced.
