Abstract
A method of manufacturing a solar cell is disclosed. The method includes forming a doping region including first and second portions having different doping concentrations by ion-implanting a dopant into a semiconductor substrate and forming an electrode connected to the doping region. In the forming of the doping region, the first and second portions are simultaneously formed by the same process using a mask that is disposed at a distance from the semiconductor substrate.
