Solar cell failure
The performance of Silicon solar cells is effected by the presence of cracks which are inevitable. These cracks exist in different patterns in the cells. Any given particular pattern of cracks leads to formation of recombination centers and insulated areas. Furthermore, these crack patterns lead to the formation of hot spots leading to the …
