Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
Additionally, another research work studied the thermomechanical behaviour of full-cell and cut-cell (half-cut and one-by-three cut cell) PV modules during production and hotspot formation [20]. The results showed that the cut cells are more resistant to thermomechanical loads and that the cell pattern and geometry highly affect the stresses.

Photovoltaic Cell is an electronic device that captures solar energy and transforms it into electrical energy. It is made up of a semiconductor layer that has been carefully processed to transform sun energy into electrical energy. The term "photovoltaic" originates from the combination of two words: "photo," which comes from the Greek word "phos," meaning …
