COMPOSITION THAT FORMS N-TYPE DIFFUSION LAYER, N-TYPE DIFFUSION LAYER MANUFACTURING METHOD AND SOLAR CELL ELEMENT MANUFACTURING METHOD

摘要

A composition for forming an n-type diffusion layer includes a glass powder containing P 2 O 5 , SiO 2 and CaO and a dispersion medium. An n-type diffusion layer and a photovoltaic cell element having an n-type diffusion layer are produced by applying the composition for forming an n-type diffusion layer on a semiconductor substrate and by subjecting the substrate to a thermal diffusion treatment.
