I want to do optical modelling with P3HT:PCBM solar cells. So how do I use AM1.5 optical source instead of the C interpreter in solarex07.in example? If I replace the C interpreter with "power.file=AM15.spec" , it gives a Voc of 6.0....e-11V which is too low. why does this happen?
Also I would like to know how to use PHOTOGEN statement in Silvaco.
Thank you in advance
