A solar cell and a method of fabricating the same are provided according to one or more embodiments. According to an embodiment, the solar cell includes a substrate, a back electrode layer formed on the substrate, a light absorbing layer formed on the back electrode layer, and a transparent electrode layer formed on the light absorbing layer, wherein the light absorbing layer is comprised of copper (Cu), gallium (Ga), indium (In), sulfur (S), and selenium (Se) and includes a first concentration region in which concentrations of sulfur (S) gradually decrease in the light absorbing layer going in a first direction from the back electrode layer to the transparent electrode layer.

Solar cell and method of fabricating the same

A method of manufacturing a solar cell having increased light efficiency due to increased gallium distribution on a surface of a light absorption layer, the method including forming a first electrode on a substrate, forming a precursor that includes at least one of copper, gallium, and indium on the first electrode, forming a preliminary light absorption layer by providing selenium to the precursor, forming the preliminary light absorption layer further including performing a heat treatment, and forming a liquid state CuSe compound, forming a light absorption layer by providing a compound including at least one of gallium and indium to the preliminary light absorption layer, and forming a second electrode on the light absorption layer.

Method of manufacturing solar cell

A solar cell module is provided. The solar cell module includes: a substrate; a plurality of unit cells including a first electrode, a semiconductor layer, and a second electrode that are sequentially deposited on the substrate; a first sub-module and a second sub-module having the unit cells, respectively; a first longitudinal pattern dividing the unit cells of the first sub-module, and a second longitudinal pattern dividing the unit cells of the second sub-module; a transverse pattern dividing the first sub-module and the second sub-module; and an insulating portion disposed near the transverse pattern, and insulating between the first sub-module and the second sub-module, wherein the unit cells of the first sub-module are connected in series through the first longitudinal pattern, the unit cells of the second sub-module are connected in series through the second longitudinal pattern, and the first sub-module and the second sub-module are connected in series through the transverse pattern.
