  • Publication number: 20130125971
    Abstract: Method of manufacturing a photovoltaic device and a photovoltaic device manufactured by using the method. The method includes forming a first conductive-type semiconductor layer using a first impurity on a semiconductor substrate, performing doping on a region of the first conductive-type semiconductor layer using a laser such that the region of the first conductive-type semiconductor layer has a higher concentration of the first impurity than a remaining portion of the first conductive-type semiconductor layer, performing edge isolation to form a groove portion at an edge portion of a rear surface of the semiconductor substrate, forming an antireflection layer on a front surface of the semiconductor substrate, forming a first metal electrode on the front surface of the semiconductor substrate, and forming a second metal electrode and a second conductive-type semiconductor layer including a second impurity that is different from the first impurity, on the rear surface of the semiconductor substrate.
