Solar cell and method for fabricating a solar cell

摘要

There is disclosed a method for fabricating a solar cell (10) comprising at least forming a phosphorus-containing junction layer (2) having a n<++> part (3) in which phosphorus is doped at high concentration on the front surface of a P type silicon substrate (1), forming a front surface electrode on the n<++> part, and forming a back surface electrode on the back surface of the P type silicon substrate, characterized in that the phosphorus-containing junction layer having the n<++> part (3) on the front surface is formed by printing an organic silica compound paste containing phosphorus on the P type silicon substrate in a pattern corresponding to a pattern of the front surface electrode (6), and subjecting the P type silicon substrate to vapor phase phosphorus diffusion heat treatment, and a solar cell fabricated by the method. There can be provided a method for fabricating a solar cell having high efficiency in high productivity
