Effects of temperature and series resistance on GaAs concentrator solar cell
Published online by Cambridge University Press: 06 February 2008
Abstract
Concentrators use reflection or refraction of light, or a combination of
both, but concentration of light leads to a crucial heating of the cell,
which involves degradation of its performance. However, solar cells
especially conceived for concentration can support very intense
illuminations as far as an active cooling is assured. In this work, a GaAs
solar cell with AlxGa$_{1-x}$As window layer, operating under low
injection conditions, has been studied with temperature and solar
concentration. The temperature corresponding to each concentration was
calculated, and then used in the calculation of photovoltaic parameters. The
study was carried out under free mode conditions (without heat sink) and
then under forced conditions (with a cooling system) in order to demonstrate
the importance of cooling in the concentrator solar cells.
The effect of series resistance on solar cell characteristics has also been
studied. The simulation was carried out using SCAPS-1D simulator. The
results were compared with those obtained theoretically; a good agreement
was found between the two models.
