Abstract
In two new single n^+(p^+)-p(n)\ X(x)-alloy junction solar cells at 300 K,\ [X(x)\equivCdS_{1-x}{\rm Se}_x, CdS_{1-x}{\rm Te}_x],0\lex\le1, by basing on the same physical model-and-treatment method, as used in our recent works [1, 2], we obtain the highest (or maximal) efficiencies, \eta_{Imax.(IImax.)}, given in the following.At x=0, \eta_{Imax.(IImax.)}=42.24 % (42.60 %) are investigated for CdS_{1-x}{\rm Se}_x alloy-junctions, as given in Tables 2.2 (3.2), and \eta_{Imax.(IImax.)}=41.92 % (42.60 %), for CdS_{1-x}{\rm Te}_x alloy-junctions, as given in Tables 4.2 (5.2), which can be compared with the corresponding ones given in the n^+(p^+)-p(n) crystalline CdS-junction solar cells [1], as: \eta_{Imax.(IImax.)}=43.22\ %\ (43.40\ %), respectively.Then, in particular, at x=1, \eta_{Imax.(IImax.)}=46.07 % (46.59 %) and T_H=556.3 K (561.7 K) are obtained for CdS_{1-x}{\rm Se}_x alloy-junctions, and \eta_{Imax.(IImax.)}=48.51 % (48.88 %) and T_H=582.6 K (586.8 K), for CdS_{1-x}{\rm Te}_x alloy-junctions, as given in Tables 4.2 (5.2), respectively, which could be found to be the new and original results. Finally, we can conclude that: (i) \eta_{Imax.(IImax.)} and T_H increase with increasing x, and (ii), for obtaining the highest efficiencies, the (CdS_{1-x}{\rm Se}_x, CdS_{1-x}{\rm Te}_x)-alloy junctions could be chosen rather than the crystalline CdS-junctions [1].
