Fast Acquisition of the Characteristics of Silicon Concentrator Solar Cells
نویسنده
چکیده
The characterisation of 85 rear-line-contacted silicon concentrator solar cells on one single wafer requires a fast, automated measurement system. In this paper an easy to use needle array measurement system is presented, which allows an automated sequential measurement of dark and light IV curves of all cells on one wafer. For acquiring IV curves under high illumination levels (up to 500 suns), a flash tester is presented, which permits measurements of cell parameters of high lifetime silicon concentrator solar cells without suffering from transient errors. This is achieved through a nearly constant voltage at the cell during one flash. The IV curves acquired with this new flash tester are in very good agreement with the ones acquired with a standard steady-state measurement setup.
