science is not as sexy as it appears on television.
My modelling career has been with the optoelectronics of third-generation solar cells, typically with Bemax, Lumerical, Comsol, Igor and Matlab. My Transfer Matrix Model for the calculation of thin-film optical inteference and photocurrent generation (via the formalism of Pettersson et al. J. Appl. Phys 1999) in matlab is freely available here (CC-BY-SA).
