Hot spot (photovoltaics)

Hot spots can origin, if one solar cell, or just a part of it, produces less carrier compared to the other cells connected in series.This may occur due to partially shading, dirt on the module (leaf, bird drop) or cell mismatches. The less producing part is only able to pass current corresponding to its own amount of carrier. Additional carrier, produced in the other cells, accumulate at the
