The Walker group has a wide range of investigative tools which we have developed such as Monte Carlo models for carrier hopping on organic polymers and molecules, drift-diffusion finite difference models for charge transport and frequency dependent models which, for instance, can describe IMPS and IMVS experiments on dye sensitized solar cells. We also perform 3D finite element simulations using the Comsol Multiphysics package.
