Solar cells are used in power electronic devices in satellites and space vehicles For good solar cell, this must be small. 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). This point is located at the “knee” of the curve. Quantum characteristics of solar cells ... of the solar cell to create a V-I source. Similarly, the open circuit voltage, Voc, is the potential that develops across the terminals of the solar cell when the external load resistance is very large (Figure 3). The "fill factor“(FF) is the parameter which, in conjunction with Voc and Isc, determines the maximum power from a solar cell. Solar cell 2. Short circuit current, Isc, flows with zero external resistance (V= 0) and is the maximum current delivered by the solar cell at any illumination level.

  • I= Isc-Io {Exp (V/Vt)-1}
