Solar cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms.
A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose

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.
In other words, a solar cell operates at its MPP when its characteristic resistance (R CH) is equal to the resistance of load (R L) [7, 9,10,11,12,13,14]. In order to understand the mechanism of parasitic loss in a solar cell, R CH is an important parameter. The R CH is equal to the inverse of slope of an I-V curve of a solar cell and is shown in Fig. 1.7. Fig.

Additionally, an elevated temperature assisted high-intensity light soaking treatment could repair the damaged silicon hydrogen bonding configurations within n-μc-SiO x:H and i-a-Si:H layers and break the electrically inactive binding of P and H atoms in the n-μc-SiO x:H layer, contributing to the performance recovery of SHJ solar cells.
The working principle of solar cells is based on the photovoltaic effect. The PV effect can be divided into three essential procedures [18, 19, 20]. Absorption of photons in a p-n junction electronic semiconductor to generate the charge carriers (electron-hole pairs).
Constructed with vertical junctions, solar cells always target favored energetics in the vertical direction to ensure efficient carrier transport across the device.
