In a perfect world we would know for each cell at every moment during production how all relevant parameters are.

The more common case in today’s PV industry instead is, that only end of line test data is available. In his presentation at WCPEC-8 Dr. Hannes Wagner-Mohnsen shows how it is still possible to derive useful information on the production even if only EOL data is available.

The World Conference on Photovoltaic Energy Conversion (WCPEC-8) is the world’s biggest platform for PV research and development.It combines the three largest and most prominent international PV conferences: the European Photovoltaic Solar Energy Conference (EU PVSEC), the Photovoltaic Specialists Conference (IEEE PVSC) and the International PV Science and Engineering Conference (PVSEC).
