Abstract: A method for manufacturing CZTS nanoparticles and CZTS nanoparticles manufactured by the same are provided. The method for manufacturing CZTS nanoparticles includes a step of preparing a precursor solution by mixing water-soluble salts containing Cu, Zn, Sn and S and water, and a step of synthesizing CZTS nanoparticles through the reaction of the precursor solution at a certain temperature. In the method, the CZTS nanoparticles may be manufactured without using a poisonous material and the method is eco-friendly. Since the CZTS nanoparticles may be manufactured by a hydrothermal synthesis using water as a solvent, the CZTS nanoparticles having high quality may be manufactured at low cost. Further, since the CZTS nanoparticles may be used as a replacing material of a common CIGS thin film solar cell, a solar cell having high efficiency may be realized at low cost.

Abstract: A solar cell having a light absorbing layer with a three-dimensional structure and a manufacturing method thereof are disclosed. The solar cell comprises: a rear electrode layer formed on a substrate; a light absorbing layer which is formed on the rear electrode layer and has a uneven surface provided by a plurality of convex portions on the surface and a plurality of concave portions formed thereby; a window layer arranged to have a p-n junction on the uneven surface of the light absorbing layer; and a buffer layer interposed between the light absorbing layer and the window layer. The conversion efficiency can be improved by generating a lot of charge transmitters since the light absorbing layer has a three-dimensional structure.
