Can a silicon solar cell break a crack?

Then, based on the air-coupled ultrasonic nondestructive testing system, the amplitude distributions of Lamb waves propagating along various rotation angles in monocrystalline silicon solar cells were extracted to construct the crack scattering pattern, and the level of crack's breaking though was evaluated.

How to detect micro cracks in photovoltaic modules?

Micro cracks degrade the power output in photovoltaic modules due to the inactive cell area. Micro-cracks are invisible to detect by naked eye and hence the Electroluminescence (EL) imaging were introduced to analyse the cracks in PV module. The electroluminescence is the most useful method to detect the cracks in the solar cell.

What happens if a solar module cracks?
