This year's annual workshop (Photovoltaik-Modultechnik in the official German), which is jointly organized by TÜV Rhineland and the Energy Agency NRW in Cologne, hosted some 150 experts from the German PV industry on Monday and Tuesday this week. The focus of the event was on topics related to increasing the lifetime of solar modules as well as the avoidance and identification of failures in photovoltaic systems. Axel Herguht from the University of Konstanz reported on the latest results on the regeneration of highly efficient PERC solar cells, which show a significant degradation in their performance within the first year of operation under illumination if they are not specially treated. Three presentations highlighted the advances in fault detection of solar modules using thermography and electroluminescence. Bernhard Weinreich ...Den vollständigen Artikel lesen ...
