Patent number: 8293567Abstract: 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: GrantFiled: January 26, 2011Date of Patent: October 23, 2012Assignee: Jenn Feng Industrial Co., Ltd.Inventor: Chuan-Lung Chuang
