Abstract: Provided is a method of manufacturing a high efficiency flexible thin film solar cell module including a see-thru pattern. The method of manufacturing a flexible thin film solar cell module includes: sequentially forming a light-absorbing layer, a first buffer layer, and a first transparent electrode layer on the release layer; forming a second buffer layer on the exposed bottom surface of the light-absorbing layer; forming a P2 scribing pattern by removing at least one portion of each of the first buffer layer, the light-absorbing layer, and the second buffer layer; forming a second transparent electrode layer on the second buffer layer and the first transparent electrode layer exposed by the P2 scribing pattern; and forming a P4 see-thru pattern by selectively removing at least one portion of the first buffer layer, the light-absorbing layer, the second buffer layer, and the second transparent electrode layer.

Abstract: A method for manufacturing a thin film solar cell includes: depositing a transparent first rear electrode on a first surface of a transparent substrate; depositing a second rear electrode having a high-conductive metal on the first rear electrode; performing a first laser scribing process to separate a double layer of the first and second rear electrodes; depositing a light absorption layer having selenium (Se) or sulfur (S) on the second rear electrode; performing a second laser scribing process by inputting a laser to a second surface of the transparent substrate to separate the light absorption layer; depositing a transparent electrode on the light absorption layer; and performing a third laser scribing process by inputting a laser to the second surface to separate the transparent electrode. Accordingly, patterning may be performed in a substrate-incident laser manner to improve price, productivity and precision of the patterning process.

Abstract: The present disclosure relates to a Se or S based thin film solar cell and a method for fabricating the same, which may improve the structural and electrical characteristics of an upper transparent electrode layer by controlling a structure of a lower transparent electrode layer in a thin film solar cell having a Se or S based light absorption layer. In the Se or S based thin film solar cell having a light absorption layer and a front transparent electrode layer, the front transparent electrode layer comprises a lower transparent electrode layer and an upper transparent electrode layer, and the lower transparent electrode layer comprises an oxide-based thin film obtained by blending an impurity element into a mixed oxide in which Zn oxide and Mg oxide are mixed (also, referred to as an ‘impurity-doped Zn—Mg-based oxide thin film’).
