Here we present an experimental study based on the electroluminescence (EL) technique showing that crack propagation in monocrystalline Silicon cells embedded in photovoltaic (PV) modules is a much more complex phenomenon.
Cracking in Silicon solar cells is an important factor for the electrical power-loss of photovoltaic modules. Simple geometrical criteria identifying the amount of inactive cell areas depending on the position of cracks with respect to the main electric conductors have been proposed in the literature to predict worst case scenarios.
Brun et al. analyzed the fracture stress of PV silicon wafers during handling and transportation. A method was proposed to analyze the silicon wafer fracture during transportation by calculating the total stress state of the wafers.
In addition, the change in microcrack morphology caused by higher wire speed and feed speed, the risk of silicon wafer fracture was further increased. In short, the rapid development of the solar-PV industry has made the problem of silicon wafer fracture increasingly prominent.
3.2.1. Fracture mode analysis The crack propagation velocity in a silicon mono-crystal was reported as 2300 ± 300 m.s − 1 and 3300 m.s − 1 by Hauch et al. (1999) and Sherman and Be’ery (2003), respectively.
For solar grade silicon plates, as the grains are visible to the naked eye, it is easy to determine the failure mode in experiments, as long as the crack pattern can be captured by an imaging device. Thus, in our 4-point bending framework, a high speed imaging technique was used in order to track the cracking process.
