Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
The equivalent circuit of a PV cell typically consists of the following components: Photovoltaic Current Source (Iph): This represents the current generated by the PV cell when exposed to light. It is proportional to the intensity of incident light and the efficiency of the cell.
The working principle of a photovoltaic (PV) cell involves the conversion of sunlight into electricity through the photovoltaic effect.

Chapter 4. The working principle of all today solar cells is essentially the same. It is based on the photovoltaic effect. In general, the photovoltaic effect means the generation of a potential difference at the junction of two different materials in response to visible or other radiation.
