Glass-glass BIPV modules as construction product: mechanical resistance and post-breakage behaviour
When applying photovoltaic (PV) modules containing glass in the building envelope, the requirements on construction safety and reliability are particularly high. To prove the mechanical resistance and stability of constructions according to the Eurocode system, the structural engineer needs mechanical performance characteristics of all construction products used. As the mechanical performance of PV modules is not adequately characterized up to now, individual approvals are still needed in various European countries. This article presents experimental research work on glass based PV modules aiming to analyze whether the integration of various types of PV cells into glass products essentially changes the material characteristics defined in the harmonized product standards. The experiments focused on two aspects: the bending strength of PV thin-film coated glass panes compared to the uncoated basic float glass product and the post-breakage behavior of laminated glass-glass PV modules compared to laminated safety glass. The standardized four point bending test equipment was modified to hold full-size thin-film PV samples and has proved suitable to determine these samples' bending strength. The integration of PV cells was observed to improve the residual strength of laminated safety glass after breakage.
