20150059845 | CZTS-BASED THIN FILM SOLAR CELL AND METHOD OF PRODUCTION OF SAME - A CZTS-based thin film solar cell which has a high photovoltaic conversion efficiency which is provided with a substrate, a metal back electrode layer which is formed on the substrate, a p-type CZTS-based light absorption layer which is formed on the metal back electrode layer, and an n-type transparent conductive film which is formed on the p-type CZTS-based light absorption layer and which has a dispersed layer of ZnS-based fine particles at the interface between the p-type CZTS-based light absorption layer and the metal back electrode layer. | 03-05-2015 |
20120258562 | METHOD OF PRODUCTION OF CIS-BASED THIN FILM SOLAR CELL - A method of production of a CIS-based thin film solar cell comprises the steps of forming an alkali control layer on a high strain point glass substrate, forming a back surface electrode layer on the alkali control layer, forming a CIS-based light absorption layer on the back surface electrode layer, and forming an n-type transparent conductive film on the CIS-based light absorption layer, wherein the alkali control layer is formed to a thickness which allows heat diffusion of the alkali metal which is contained in the high strain point glass substrate to the CIS-based light absorption layer and, furthermore, the CIS-based light absorption layer has an alkali metal added to it from the outside in addition to heat diffusion from the high strain point glass substrate. | 10-11-2012 |
20100037945 | BLACK-CERAMIC-DECORATED SOLAR CELL MODULE - The electrode parts of a solar cell module which differ in color form other parts of the module are hidden without increasing the number of module assembly/production steps to thereby enable the whole CIS based thin-film solar cell module to have an even color throughout and hence an improved appearance. | 02-18-2010 |
20090095347 | CIS BASED THIN-FILM SOLAR CELL MODULE HAVING PATTERN-DISPLAYING FUNCTION AND PROCESS FOR PRODUCING THE SAME - A design pattern or the like is displayed on a module at low cost through simple production steps without reducing the reliability and conversion efficiency of the module to thereby improve an aesthetic sense and obtain an advertising effect. A resin film F bearing a cutout display pattern, e.g., a design, is sandwiched between a CIS based thin-film solar cell submodule | 04-16-2009 |
20080271781 | Cis Type Thin-Film Solar Cell and Process for Producing the Same - This invention provides a CIS-based thin film solar battery and a process for producing the same in which the formation of an alkali barrier layer and a metal backside electrode layer is carried out at a low cost in a short time to prevent such an unfavorable phenomenon that a light absorbing layer is separated from the interface of the light absorbing layer and the metal backside electrode layer. The CIS-based thin film solar battery ( | 11-06-2008 |
