Test device for automatic concentrator solar cell wafer

A test device for automatic concentrator solar cell wafer is disclosed, which uses a solar simulator or an instrumental light bulb in general as the light source in the test device, then adds a concentrator module to boost the density of incident light energy from the surface of to-be-tested solar cell. The test device coordinates with a displacement platform, a transporting body, an electrical measuring device and a computer so as to use master program in the computer that is capable to execute testing on the concentrator solar cell wafer, and with an accurate displacement between the displacement platform and the transporting body The test device is able to conduct testing in speedy and efficient manner on the concentrator solar cell wafer for various important parameters including open-circuit voltage (Voc), short circuit current (Isc), maximum power voltage (Vmax) and maximum operating current (Imax) so that the fill factor and photo-electric conversion efficiency of the concentrator solar cell wafer can
