Method of manufacturing point contact solar cells and apparatus using the same

Abstract

An apparatus of manufacturing high-efficiency solar cells by reducing contact resistance and forming point contacts is disclosed. The apparatus includes a carrying device configured to support a solar cell, a conducting module electrically connected to the solar cell optionally, a pulsed power supply used to provide a high frequency pulsed voltage that is a reverse bias voltage and has a frequency of about 1 kHz to 10 MHz and a duty cycle of about 5% to 95%, and a light source. As the pulsed power supply applies the high frequency pulsed voltage to the solar cell via the conducting module, the light source illuminates the solar cell at a power density of 10 W/m2 above and scans the solar cell. Thereby discontinuous conductive regions are formed in the solar cell.
