Development and testing of light-weight PV modules based on glass-fibre reinforcement

In this paper we report on our approach on integrating c-Si PV into lightweight structures, in particular towards vehicle integration. To this end we want to get rid of the (bulk weight of the) glass but seek a suitable replacement in terms of mechanical stability. First we elaborate on the most basic standards and norms that VIPV products should relate to in terms of (thermo-)mechanical testing. Then, for the experimental part, 2 concepts are investigated. In a first approach, we reinforced the encapsulant with glass fibre material, while in a second one we applied a dedicated glass-fibre-reinforced sheet as a replacement of the backsheet. In both cases we stay as close as possible to using commercially available material. For each approach we elaborate the testing that has been carried out: thermal cycling, vibrations, mechanical shock and hail impact. On a final note, we point out some initial damp heat testing results, that are a particular challenge for light-weight modules without glass.
