摘要
Abstract The ability to quantify internal strain levels within a photovoltaic (PV) laminate is essential to aid in the development of reliable and sustainable PV modules. This need is even greater for emerging applications with a high degree of integration such as vehicle and infrastructure integrated PV. Within this work, we demonstrate a scalable optical sensing solution, which allows for the in situ thermo‐mechanical strain and temperature monitoring of photovoltaic modules. Using a combination of two optic fibers with fiber Bragg gratings (FBGs) with a different packaging, an absolute in‐laminate temperature accuracy of 0.3°C has been achieved along with the ability to detect changes in strain as low as 0.248 μϵ. The sensor solution provides the potential to monitor and quantify various failure modes or degradation at various stages in the development process up to in‐field monitoring. Furthermore, it provides a platform for the direct validation of physics‐based simulations.
