Abstract
A solar cell and a method of manufacturing the same are disclosed. The solar cell includes a semiconductor substrate, a first semiconductor region positioned at a front surface or a back surface of the semiconductor substrate and doped with impurities of a first conductive type, a first electrode connected to the first semiconductor region, and a second electrode connected to the back surface of the semiconductor substrate. The second electrode is formed of a metal foil, and an air gap is formed between the second electrode formed of the metal foil and the back surface of the semiconductor substrate.
