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: Provided are a solar cell including phosphor and a method for manufacturing the same. The solar cell includes a lower electrode, a pattern phosphor layer which is arranged on the lower electrode, a light absorption layer which is arranged in the front surface of the pattern phosphor layer, a transparent electrode which is arranged on the light absorption layer, and an upper electrode which is arranged on the transparent electrode. The method of manufacturing the solar cell includes a step of forming an lower electrode on a substrate, a step of forming a pattern phosphor layer on the lower electrode, a step of forming a light absorption layer in the front surface of the pattern phosphor layer, a step of forming a transparent electrode layer on the light absorption layer, and a step of forming an upper electrode on the transparent electrode layer. After the light of a specific wavelength range which is reflected from the lower electrode without the absorption of the light absorption layer is absorbed, it is changed into light of a visible ray wavelength range of about 500 nm-800 nm to supply it to the light absorption layer. Thereby, the photocurrent density of the solar cell is increased. Thereby, the photoelectric transformation efficiency can be improved.

Abstract: The present invention relates to a solar cell including a fluorescent substance and a manufacturing method thereof. The solar cell including a fluorescent substance includes a rear side electrode, an optical absorption layer, a buffer layer, a window layer and a front side electrode laminated in serial order. The optical absorption layer includes fluorescent substance at a steady rate so that the photocurrent density is increased, and photoelectric transformation efficiency of the solar cell is improved. Meanwhile, the manufacturing method of solar cell including fluorescent substance comprises the following steps: forming a back side electrode on the substrate; forming the optical absorption layer including fluorescent substrate on the back side electrode; forming the buffer layer on the optical absorption layer; forming the window layer on the buffer layer; and forming the front side electrode on the window layer. Therefore, a separate layer including a fluorescent substance does not need to be arranged. With a simple method of including a fluorescent substance directly in the optical absorption layer, the photoelectric transformation efficiency of the solar cell can be improved.
