Abstract
A solar cell is disclosed. The solar cell includes a first conductive region positioned at a front surface of a semiconductor substrate and containing impurities of a first conductivity type or a second conductivity type, a second conductive region positioned at a back surface of the semiconductor substrate and containing impurities of a conductivity type opposite a conductivity type of impurities of the first conductive region, a first electrode positioned on the front surface of the semiconductor substrate and connected to the first conductive region, and a second electrode positioned on the back surface of the semiconductor substrate and connected to the second conductive region. Each of the first and second electrodes includes metal particles and a glass frit.
