Abstract:
The limited efficiency of the multijunction solar cells using a thermodynamic approach to calculating the efficiency
has been estimated. According to the performed studies, the efficiency of single-junction solar cells for the studied materials
does not exceed 50%. An increase from one to six in the number of p−n junctions leads to an increase in the efficiency of solar
radiation conversation from ∼18,2% to ∼62,5% (when derating factor is equal to 0,8) and from ∼20,2% to ∼55,5% (when
derating factor is equal to d=0,7…0,89). It is shown that the solar cells with six p−n junctions are the most optimal in terms of
efficiency.
