Publication number: 20100243043Abstract: A light absorbing layer of a CIGS solar cell and a method for fabricating the same are provided. According to the present invention, a cuprous sulfide layer is prepared by a sputtering process. Then, a CIGS sol-gel solution is provided onto the cuprous sulfide layer by an immersion coating, spin coating, printing, or spray coating process. The CIGS sol-gel solution is then baked to form a plurality of a CIGS stack layers containing copper (Cu), indium (In), gallium (Ga), and selenium (Se). A rapid thermal process is then conducted for melting the cuprous sulfide layer and the CIGS stack layers to form a copper/indium/gallium/sulfur/selenium (CIGSS) light absorbing layer. The CIGSS light absorbing layer is provided for a solar cell to improve the photoelectric transformation efficiency and the light absorbance.Type: ApplicationFiled: March 25, 2009Publication date: September 30, 2010Inventor: Chuan-Lung Chuang

Publication number: 20100236616Abstract: A copper/indium/gallium/selenium (CIGS) solar cell including a thermal expansion buffer layer, and a method for fabricating the same are provided. The thermal expansion buffer layer is configured between an alloy thin film layer and a CIGS thin film layer. The thermal expansion buffer layer is deposited by executing a thin film deposition process with a continuous sputtering machine bombarding a cuprous sulphide (Cu2S) or cuprous selenide (Cu2Se) target. Then, a CIGS thin film is further provided on the thermal expansion buffer layer. Finally, a thermal treatment is conducted for melting to integrate the copper ingredients of different thin film layers, thus improving the bondability between the thin film layers and preventing the cracking or the peeling off of the thin film layers caused by the thermal expansion difference.Type: ApplicationFiled: March 19, 2009Publication date: September 23, 2010Applicant: JENN FENG INDUSTRIAL CO., LTD.Inventor: Chuan-Lung Chuang

Patent number: 7622161Abstract: A method of making a coated article (e.g., window unit), and corresponding coated article are provided. A layer of or including diamond-like carbon (DLC) is formed on a glass substrate. Then, a protective layer is formed on the substrate over the DLC inclusive layer.
