We have some very complex software for simulation and modelling, I observe that student take a lot of time just for understanding and simple know how operation of the standard software. Which is not required for one or two semester undergraduate project.
We can use the OPV tool to simulate P3HT:PCBM solar cells. It would be great if we could extend it further to BHJ OSCs.
Yes, I agree. However, BHJ has very unusual active layer morphology and writing a generic tool for that is difficult. You can always start with the effective media approach as described by Koster et al. (http://prb.aps.org/abstract/PRB/v72/i8/e085205).
In SILVACO software the simulation of organic materials exists. you can get the free version 2007 on thesite www. RAPIDSHARE.com . it is a powerful simulation tolls for devices.
Using simple molecular modeling, one can derive hole mobility in organic semiconductors using Deng & Goddard's approach to Marcus theory:

Using this simple approach should enable a 1-2 semester project.
