The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device. The theoretical studies are of practical use because they predict the fundamental limits of a solar cell, and give guidance on the phenomena that contribute to losses and solar cell efficiency.
AI Customer ServiceThe generation of current in a solar cell, known as the "light-generated current", involves two key processes. The first process is the absorption of incident photons to create electron-hole pairs. Electron-hole pairs will be generated in the solar cell provided that the incident photon has an energy greater than that of the band gap.
Basically, the solar cells can be combined to satisfy a wide range of the load requirement concerning current, voltage, and power. A large solar cell array is subdivided into smaller arrays called the solar cell panels, which are composed of modules. Then a large array is built from modules.

The equivalent circuit of solar cell. In this model, the current source represents Iph, the current passing in the diode represents the dark current, while Rs and Rsh represents series resistance and the shunt resistance of the solar cell. This equivalent circuit is that of a real diode added to it the photogenerated current Iph.
5. The PV Arrays In the previous sections, we have seen that the driving voltage of a single solar cell is about 0.55 V, and its current is about 35 mA/cm 2 for AM1 illumination. Conventional loads demand more voltage, more current, and more power.
The incident sunlight is focused or guided by optical elements such that a high intensity light beam shines on a small solar cell. Concentrators have several potential advantages, including a higher efficiency potential than a one-sun solar cell and the possibility of lower cost.
