Numerical Modeling of the Effects of Excitons in a Solar Cell Junction n+p of the Model by Extending the Space Charge Layer

Abstract

In this study we analyze the numerical distribution of the density of electrons and excitons in a solar cell junction n+p of the model by extending the space charge zone. It is subject to monochromatic illumination on the front side (transmitter) and the thermally insulated back panel. Equations governed by phenomena of transport of minority charge carriers and excitons following excitation are coupled to the heat. They are discretized with the finite difference method and are solved with finite volume method. The development of a computer code gave results in good agreement with those obtained by other authors and may also enable better control performance solar cells, for their improvement. We present the results for different values of the factor and the coefficient of heat flux coupling.
