7-IV Series Solar Cell IV Tester
Product Introduction：
Under a certain solar light, the test of Solar cell I-V characteristic is to output a relative curve of the current and the voltage loaded. IV characteristic can fully express the conversion efficiency of solar cells,and can get the final performance index of cells. The final performance index provides the basis for theproduction of components and for determining the price.SoFn Instruments Co., Ltd provides solar cell IV measurement system with a scientific grade and related equipment and the products will be suitable for research, test and evaluation of various optoelectronic materials, photovoltaics parts and solar cells
