Profile

Reliability, service life and optimum performance: Aiming lower costs, these parameters are most important and challenging for any module manufacturer. The integral research topics within the group »Module Reliability« at Fraunhofer CSP apply to those challenges. Major topics are the characterization of solar modules, module components and materials. Those topics are faced by an integral strategy of material science based analysis. This comprises mechanical experiments and characterization methods on component and module level, mechanical and thermo-mechanical Finite Element Analysis as well as performance tracking on laboratory basis and at locations outdoor. The aim of this strategy is the investigation of various reliability aspects and the optimization of those. Material and technological processes derived from these are extended in cooperation with the group »Module Technology«. This first hand approach of material science combined with experiments and modeling offers a unique and comprehensive support of partners and customers within the R&D processes.
The »Module Reliability« group is involved within the major solar module based projects of the »Excellence Cluster Solarvalley Mitteldeutschland« as well as the »Innovationsallianz Photovoltaik« of the Federal Ministry of Education and Research. Amongst others those projects deal with the integration of various solar cell technologies into solar modules as well as mechanical reliability of thin film modules and BIPV. In a project with the Institute IRESEN in Morocco, the group »Module Reliability« is concerned with the realization of an outdoor test field for regional PV development.
