摘要:
The composition for forming an n-type diffusion layer in accordance with the present invention contains a donor element-containing glass powder and a dispersion medium. An n-type diffusion layer and a photovoltaic cell having an n-type diffusion layer are prepared by applying the composition for forming an n-type diffusion layer, followed by a thermal diffusion treatment.
