Abstract
The composition for forming a composition for forming a p-type diffusion layer, the composition containing a glass powder and a dispersion medium, in which the glass powder includes an acceptor element and a total amount of a life time killer element in the glass powder is 1000 ppm or less. A p-type diffusion layer and a photovoltaic cell having a p-type diffusion layer are prepared by applying the composition for forming a p-type diffusion layer, followed by a thermal diffusion treatment.
