Materials Behaviors Based Solar Cell Performance Analysis

Abstract

In this research solar cell efficiency has been increased by swapping several type of cell materials with different thickness and materials behaviour has been observed by analyzing consumption of photon by the semiconducting materials. It is possible to increase the efficiency of solar cell by changing materials or layer structure, every material consists of individual characteristics, as a result materials attributes has been analyzed in many ways. In this thesis, all the cell structures consists of seven layer, the material has been changed by layer and thickness, same material used for several example by changing position of the material or thickness and every material characteristic have been showed by graphical illustration. And finally, discussed about a material or a structure model by analysis in several aspects. Setfos software has been used to simulate this task, setfos is very effective software for solar cell and LED analysis and simulation, for his some special attributes like individual layer structured is possible by using setfos with separate parameter for every layer which was very helpful to analysis deeply. In this case, it has been studied about the solar cell structure to analysis efficiency by changing cell materials, tried to observed the material behaviour with individual graphical illustration. Here many types of material behaviour has been showed namely, electrical profile, optical profile and spectral profile. For all the example here simulating software parameters like, humo value, lumo value, incoherent, isotopic, transparent, wavelength, voltage, temperature, polarity, tapping, doping, mobile ions, electrons density, hole density etc never changed, all the values are retains default only cell materials related parameters has been changed to analysis material behaviour which is mention below table with every example.
