Product Applications

   Among all the performance characterization means of solar photovoltaic devices, IV characteristic test is undoubtedly the most intuitive, effective and widely used one. By measuring the IV characteristic curve and further analyzing the data, we can directly understand the physical properties of PV devices, including the efficiency of photoelectric conversion and fill factor. These data can provide a reliable basis for the research, quality control and application of PV devices. We provide cost-effective IV characteristic testing system and the most complete and professional technical support.
