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).

When a photon hits a piece of semiconductor, one of three things can happen: 1. The photon can pass straight through the semiconductor — this (generally) happens for lower energy photons.2. The photon can reflect off the surface.3. The photon can be absorbed by the semiconductor if the photon energy is higher than the band gap value. This generates an electron-hole pair and some

Theory of Solar Cells

If you connect PV modules together, you make a photovoltaic panel (or solar panel). Join several PV panels together, and you get a photovoltaic array (or solar array). In this way, the hole (or a missing electron) can be thought of as a positive charge that can move around the lattice, which is why this doping is called p-type. The bonding
