you used a x value in the intervall {1.69879}{3.301} but it must be


R_{sp\acute{e}cifique}\left(\frac{\Omega}{cm^2} \right)$,
   ysubticks=9] {->}(1,-4)(3.301,1.18){11cm}{6cm}
\psplot[linecolor=darkgray,linestyle=dashed]{1.69879}{3.301}{5.93e-9 320 
x exp mul log}
\psplot[linecolor=green,algebraic]{1.69879}{3.301}{ log( 
5.93e-9*(10^x)^2.5 )}
