Abstract

Photovoltaics (PV) is a method of converting solar energy into direct current electricity using semiconducting materials that exhibit the photovoltaic effect. Cracking in PV panels can cause performance degradation in PV panels. In this study, a new computational methodology, peridynamics is utilised to investigate the cracking behaviour in PV panels. Peridynamics is based on integro-differential equations, and it is a very suitable technique to model crack initiation and propagation. Majority of PV panels are based on silicon solar cell technology. Therefore, polycrystalline material behaviour of silicon is explicitly considered in the model. The numerical framework can be used to support the design of high-performant, long-lasting and fracture-resistant PV panels. The results can also be used to produce practical guidelines aimed to facilitate the decision of PV module rejection due to cracking during production.
