Abstract
The present manuscript is a revised form of that, with MN: 14473) In our recent works [1, 2], by basing on: (1) the effects of heavy(light) doping and donor (acceptor), d(a), size , which affect the total carrier-minority saturation current density J_{oI(II)}\equivJ_{En(p)o}+J_{Bp(n)o},\ J_{En(p)o}(J_{Bp(n)o}),\ being injected respectively into the heavily doped donor (acceptor)-GaAs emitter-lightly doped acceptor (donor)-Si base regions, HD[d(a)-Si]ER-LD[a(d)- Si]BR, of n^+(p^+)-p(n) junction solar cells, respectively, (2) an effective Gaussian donor-density profile to determine J_{En(p)o}, and (3) the use of two experimental points, we investigated the photovoltaic conversion factor n_{I(II)}, short circuit current density J_{scI(II)}, fill factor F_{I(II)}, and finally efficiency \eta_{I(II)}. Then, the limiting highest efficiencies, 31% (30.65%), were obtained in n^+(p^+)-p(n) junction solar cells at 300K. In the present work, by basing on such a treatment method, and using the physical conditions such as: W=15\ \mu m,{\ N}_{Sb(In)}={10}^{19}\ ({10}^{20})\ {\rm cm}^{-3}\ and\ S\ =100\ (cm/s\ ), according to the highly transparent HD[Sb(In)-GaAs]ER, and then N_{In(Sb)}={10}^{18}\ ({10}^{17}){\rm cm}^{-3} for LD[In(Sb)-GaAs]BR, of n^+(p^+)-p(n) junction solar cells, we get respectively the maximal values of \eta_{I(II)}, \eta_{I(II)-max.}=31.474% (44.359%), as those observed in Tables 3 et 5, which can be compared with the result of \eta=29.1\ %, obtained for GaAs-thin film cell, and \eta=45.7\ %, for GaInP/GaAs/GaInAs/GaInAs multijunction cell, by Green et al. [3].
