HETERO-JUNCTION SILICON SOLAR CELL AND FABRICATION METHOD THEREOF

摘要

A hetero-junction silicon solar cell and a manufacturing method thereof are provided to obtain high short-circuit current, a high filling rate, a rapid process time, and a low manufacturing cost by using an existing diffusion method. A hetero-junction solar cell is composed of a crystalline silicon substrate(201) and a passivation layer(203). The passivation layer is formed on an upper part of the crystalline silicon substrate. The passivation layer doped with impurities. The crystalline silicon substrate is formed with a p type crystalline silicon substrate and the impurities are composed of n type impurities. The crystalline silicon substrate is formed with an n type crystalline silicon substrate and the impurities are composed of p type impurities.
