Hetero-junction silicon solar cell and fabrication method thereof

Abstract

Disclosed are a hetero-junction silicon solar cell and a fabrication method thereof. The hetero-junction silicon solar cell according to the present invention forms a pn junction of a crystalline silicon substrate and a passivation layer doped with impurities so as to minimize a recombination of electrons and holes, making it possible to maximize efficiency of the hetero-junction silicon solar cell. The present invention provides a hetero-junction silicon solar cell comprising a crystalline silicon substrate and a passivation layer that is formed on the crystalline silicon substrate and is doped with impurities.
