In all questions surrounding the quality and aging behavior of PV module materials, it is crucial to identify relevant parameters (degradation indicators). Such degradation indicators can then be used to develop models of degradation reaction kinetics. Our work is focused on the (further) development of testing procedures – that are non-destructive if possible. In addition to outdoor exposure and accelerated aging tests, numerical simulation techniques allow us to study the degradation processes in solar thermal components, for example by calculating material and energy transport processes over the long expected service lives. Our work primarily concentrates on investigating the long-term stability of materials for use in Photovoltaic systems, particularly polymeric materials, but also covers a range of issues from diverse fields that experience similar loads and utilize other material classes.
An interdisciplinary team of scientists, engineers and technicians works closely together to produce tailored responses to various questions in degradation analysis.
