Hi John,

i´ve already found less information about the shooting method. Do you 
have some more informations for me? Than i think i´ll give it a try.
I´ll try now to describe the bvp. The ode describes  "electrone/hole 
density" in the conducting and  valence band of a polymer thin film. The 
boundary values are, that the density on the front and back have to be
