20130076382 | Apparatus and Method for Measurement of Radiation Intensity for Testing Reliability of Solar Cell, and Method for Testing Reliability of Solar Cell - An apparatus and method for measurement of radiation intensity for testing reliability of a solar cell, and a method for testing the reliability of the solar cell. The apparatus includes a first solar cell receiving a predetermined intensity of radiation or more to generate electricity, a second solar cell receiving a predetermined intensity of radiation or more to generate electricity; a temperature sensor sensing a temperature of the second solar cell; a cooler cooling the first solar cell; and a controller measuring the intensity of radiation applied to the first solar cell, and controlling the cooler to prevent the temperature of the first solar cell from increasing above a predetermined temperature depending on the temperature of the second solar cell sensed by the temperature sensor. | 03-28-2013 |
20140065760 | METHOD OF FORMING ZINC OXIDE PROMINENCE AND DEPRESSION STRUCTURE AND METHOD OF MANUFACTURING SOLAR CELL USING THEREOF - A method of forming a nanometer-scale prominence and depression structure on a zinc oxide thin film in a wet-etching method, and the method includes the steps of: preparing a substrate; forming a nano structure having a height and a width of a nanometer range; forming the zinc oxide thin film on the substrate on which the nano structure is formed; and wet-etching the zinc oxide thin film, in which in the wet-etching step, zinc oxide having relatively low physical compactness is preferentially etched since the zinc oxide is positioned on the nano structure, and thus the prominence and depression structure is formed around the nano structure by the etching. | 03-06-2014 |

20150114466 | CIGS Solar Cell Having Flexible Substrate Based on Improved Supply of Na and Fabrication Method Thereof - A CIGS solar cell having a flexible substrate based on improved supply of Na. The CIGS solar cell includes a substrate formed of a flexible material, a rear electrode formed on the substrate, a CIGS light-absorption layer formed on the rear electrode, a buffer layer formed on the CIGS light-absorption layer, and a front electrode formed on the buffer layer, wherein the rear electrode comprise a single-layered Na-added metal electrode layer. A single-layered Na-added Mo electrode layer, specific resistance of which is about 1/10th the specific resistance under conditions of a process of forming a typical multilayer rear electrode, is applied to the rear electrode, thereby providing a CIGS solar cell having a flexible substrate and high conversion efficiency. | 04-30-2015 |
20150162480 | METHOD OF MANUFACTURING CI(G)S-BASED THIN FILM HAVING REDUCED CARBON LAYER, THIN FILM MANUFACTURED BY THE METHOD, AND SOLAR CELL COMPRISING THE THIN FILM - Disclosed is a method of manufacturing a CI(G)S-based thin film, in which a slurry prepared by mixing two or more kinds of binary nanoparticles containing CI(G)S-based elements, a solution precursor containing a CI(G)S-based element, an alcoholic solvent and a chelating agent is used to reduce the carbon layer formed between the CI(G)S-based thin film and molybdenum, and which includes (a) mixing two or more kinds of binary nanoparticles containing CI(G)S-based elements, a solution precursor containing a CI(G)S-based element, an alcoholic solvent and a chelating agent, thus preparing a slurry; (b) subjecting the slurry to non-vacuum coating, thus forming a CI(G)S-based thin film; and (c) subjecting the CI(G)S-based thin film to selenization heat treatment. | 06-11-2015 |
