EFFECT OF EXCITONS ON THE EXTERNAL QUANTUM EFFICIENCY OF THE INORGANIC SOLAR CELLS BASED ON SILICON
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 4
Abstract
Exciton dissociation in solar cells, based on inorganic materials, is easily done under the effect of the electric field and the average temperature. Our study is oriented inorganic solar cells because of their high photovoltaic properties, in particular the charge carriers generating the quantum efficiency. The electron continuity equations and exciton coupled, governing generation-recombination mechanisms and diffusion after a monochromatic illumination from the front face and a thermal insulation from the back face of the cell and the heat equation were resolved by a numerical approach based on the finite volume method. These mechanisms are analyzed through the profile of the external quantum efficiency, calculated for different values of the absorption coefficient. The effects of the heating factor, the volume coupling coefficient and the surface conversion velocity on the external quantum efficiency were analyzed.
