Can c-Si wafers be used for solar cells?

Solar cell (module) characterization Next, we fabricated the foldable c-Si wafers into solar cells. The most widely used industrial silicon solar cells include passivated emitter and rear cells18, tunnelling oxide passivated contact19solar cells and amorphous–crystalline silicon heterojunction20(SHJ) solar cells.

Why do solar cells crack?

This stress can result from manufacturing, transportation phase to the PV site, installation process, or heavy snow and physical damage to the modules. Optimizing these processes can reduce cell cracking; cracks during production are unavoidable. The crack issue in solar cells becomes worse as the thickness of the wafer is being reduced 5.
