Fraunhofer’s Contactless Method To Gauge Solar Cell Efficiency Updated On Tue, May 6th, 2025 by Saurenergy Fraunhofer Institute Research scientists for Solar Energy Systems ISE havedeveloped a measurement method to determine the performance of back-contacted solar cells without contact in the production line. Measuring the current-voltage characteristic curve is the most important test in solar cell quality control. Eliminating physical contact with the solar cell saves time and thus allows significantly […] Read more
