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 2):
The solar cell according to  claim 1 , comprising a passivation film formed on the impurity diffusion layer, wherein\n the first electrode is embedded in the passivation film, and the second electrodes are formed on the passivation film and the first electrodes.
