Photovoltaic Cells – solar cells, working principle, I/U ...
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.

The data in Figure 4.2 show how the maximum efficiency of a solar cell depends on the band gap. If the band gap is too high, most photons will not cause photovoltaic effect; if it is too low, most photons will have more energy than necessary to excite electrons across the band gap, and the rest of energy will be wasted.

What are Hotspots in Solar Panels?
If the series of cells is short-circuited, it results in a high reverse polarization in the shaded cell, leading to substantial power dissipation and overheating. Since solar cells are connected in series, if even one cell or group of cells doesn''t receive enough light, it affects the energy production of all cells in the same string.
