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.
In essence, a photovoltaic cell is a high-tech method of converting sunlight into electricity. ... ... Solar cells, as an energy converter, works on the Photovoltaic effect, which aids in the direct conversion of sunlight into electricity, with the potential to meet future energy demands .
Separation of Charges: Due to the built-in electric field within the PV cell (created by the junction between different semiconductor layers), the newly generated electron-hole pairs are separated. Electrons are pushed towards the n-type (negative) side of the cell, while holes are pushed towards the p-type (positive) side.
Back Surface Field: Some advanced PV cells may incorporate a back surface field to enhance the collection of electrons and improve overall efficiency. The working principle of a photovoltaic (PV) cell involves the conversion of sunlight into electricity through the photovoltaic effect. Here's how it works:
Its primary function is to collect the generated electrons and provide an external path for the electrical current to flow out of the cell. The characteristics of Photovoltaic (PV) cells can be understood in the terms of following terminologies:
