Abstract
Exciton dissociation in solar cells, based on
inorganic materials, is easily done under the effect of the
electric field. They exhibit strong photovoltaic properties,
in particular the generation of quantum efficiency of the
charge carriers. The electron continuity equations and
exciton coupled, governing generation-recombination
mechanisms and dissemination after a monochromatic
illumination from the front side and a thermal insulation
from the back side 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
total photocurrent density, calculated for different values
of the average temperature.
The effects of the heating factor, the number of Fourier
and the surface conversion velocity on the total
photocurrent density were analyzed.
In the end, a comparison between the total photocurrent
densities, calculated as functions of these two forms
coupling coefficients volume fixed and different in the
base, was also proposed. This study allowed us to
achieve our objective, namely the development of a
numerical model applicable to inorganic solar cells.
