**Abstract**

In the n^+(p^+)-p(n) crystalline Si-junction solar cells, by basing on a same treatment method, and for a same heavy (low) doping effect, as those given in our recent paper (RP) [1], but using now a new expression, obtained for the relative dielectric constant \varepsilon\left(r_{d\left(a\right)}\right), determined exactly in the effective Bohr model, as that given in Eq. (1c), representing the donor (acceptor) d(a)-radius r_{d\left(a\right)}-effect or the \varepsilon\left(r_{d\left(a\right)}\right)-effect, suggesting further that, for an increasing r_{d\left(a\right)}, \varepsilon\left(r_{d\left(a\right)}\right) decreases, as showed in Table 1, according to the increase in photovoltaic efficiency η, as observed in Tables 2 and 3, we finally get in our present paper, for highest values of r_{d\left(a\right)}, the new limiting highest efficiencies, η=28.68% (29.87%)<\eta_{RP}=31% (30.65%), being due to r_{d\left(a\right)}\ [8]
