Fraunhofer develops contactless method for measuring back-contact solar cells

Scientists at the Fraunhofer Institute for Solar Energy Systems ISE have developed a contactless method to measure the performance of back-contact solar cells, enabling in-line assessment of key parameters such as efficiency, fill factor, and current-voltage characteristics. Scientists at the Fraunhofer Institute for Solar Energy Systems ISE have cultivated a method for measuring the performance of back-contacted solar cells that avoids contact in the production line. The method is based on photoluminescence and contactless electroluminescence images under different excitation conditions, as well ...
