Анотація Multijunction solar cells for concentrator photovoltaic (CPV) systems have attracted increasing attention in recent years for their very high conversion efficiencies. But there is a problem in this type of solar cells (CPV) is to increase the temperature if it has been augmenting the concentration ratio. In this paper, we studied the effect of the concentration photovoltaic in a high-efficiency double-junction devices solar cell on temperature solar cell and its impact on the photocurrent, the efficiency and open circuit voltage. In this study, the top cell is made of AlGaAs (1.73 eV) while the bottom cell is made of GaAs (1.42 eV) between them a tunnel junction.
