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 $\sim 18,2\%$ to $\sim 62,5\%$ (when derating factor is equal to $0,8$) and from $\sim 20,2\%$ to $\sim 55,5\%$ (when derating factor is equal to $d = 0,7 \dots 0,89$). It is shown that the solar cells with six $p-n$ junctions are the most optimal in terms of efficiency.
Keywords: analytical model, thermodynamic approach, solar spectrum, derating factor, bandgap, $p-n$ junction, limited efficiency.
