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: Disclosed is a conjugated polymer for an organic solar cell. The proportion of units containing no alkyl thiophene moieties in the conjugated polymer can vary to make the conjugated polymer suitable for use as an electron-donating organic semiconductor material in a small-area or large-area organic solar cell. Therefore, the use of the conjugated polymer ensures high energy conversion efficiency of the organic solar cell.

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.
