Parameters of a Solar Cell and Characteristics of a PV Panel

Related Post: How to Design and Install a Solar PV System? Working of a Solar Cell. The sunlight is a group of photons having a finite amount of energy. For the generation of electricity by the cell, it must absorb the energy of the photon. The absorption depends on the energy of the photon and the band-gap energy of the solar semiconductor material and it is expressed in electron-volt (eV).

Photovoltaic Effect: An Introduction to Solar Cells

The solar cell is the basic building block of solar photovoltaics. The cell can be considered as a two terminal device which conducts like a diode in the dark and generates a photovoltage when charged by the sun.
