Abstract:
A solar cell includes an n-type semiconductor substrate having a p-n junction and a back-surface side impurity-diffusion layer. The back-surface side impurity-diffusion layer is formed on a light-receiving surface of the semiconductor substrate or surface layer on a back-surface side opposite to the light-receiving surface, and has back-surface side high-concentration impurity-diffusion layers each of which contains an n-type or p-type impurity element at a first concentration and a back-surface side low-concentration impurity-diffusion layer which contains an impurity element of the same conductivity type as a conductivity type of the back-surface side high-concentration impurity-diffusion layers at a second concentration lower than the first concentration. The solar cell includes back-surface first electrodes formed at locations on a back-surface of the semiconductor substrate and electrically connected to the back-surface side high-concentration impurity-diffusion layers and back-surface second electrodes electrically connecting the back-surface first electrodes while being separated from the back-surface side impurity-diffusion layer.

Claim (Index 4):
