Maximal Efficiencies in New Single GaAs 1−x Sb x-Alloy Junction Solar Cells at 300 K

Abstract

In single n+(p+)−p(n) [X(x)≡GaAs1−xSbx]-alloy junction solar cells at 300 K, 0≤x≤1, by basing on the same physical model and the same treatment method, as those used in our recent work (Van Cong et al., 2023; Van Cong, 2023), we will investigate the highest (or maximal) efficiencies, ηImax.(IImax.), obtained at the open circuit voltage Voc(=VocI(ocII)), according to highest hot reservoir temperatures TH(K), obtained from the Carnot efficiency theorem, being proved by entropy law. Here, one first remarks that, with increasing x=(0, 0.5, 1), (i)- from Table 3, for the single n+−p X(x)-alloy junction solar cell and for given rSn(Cd)-radius, for example, ηImax.(↘)= 31.14%, 28.72%, 25.36%, according to TH(K)=
