6 FAQs about [Experimental error of solar cells]
Why is it difficult to recognize a defect on a solar cell?
Because the finger lines are as emblems and located on background of solar cell, definitely any defect (crack, hole, etc.) is appeared on the finger lines or background. In this case, defect recognition is more challenging due to misdetection.
How do mechanical defects affect the quality of solar cells?
Solar cells or photovoltaic systems have been extensively used to convert renewable solar energy to generate electricity, and the quality of solar cells is crucial in the electricity-generating process. Mechanical defects such as cracks and pinholes affect the quality and productivity of solar cells.
