$ifsolargen

$ifsolargen is a serious command for a simple solar cell simulation. The idea is the program read in solar spectrum through the command $ifsolarspectrum. If user want to use the idea absorption coefficient, he needs to use $\alpha_0$. Using $\alpha_0$, we assume that

 $\alpha(E=\hbar\omega) = \alpha_0 \times \sqrt(E-Eg)$ 

If the user needs to use absorption table to define the absorption coefficient, he can assign $absorbtable.

For example

$ifsolargen
$\alpha_0$ 

$ifsolargen, $solarstrength, $SolarSurfaceRM, $absorbtable, $ifsolarspectrum
