Multiscale simulation of solid state dye sensitized solar cells including morphology effects

In this work we present a multiscale simulation of a solid state dye sensitized solar cell including the real morphology of the active layer. In order to include the real morphology the device domain is split into two different regions: one treated using an effective material approximation and another one using the real structure of the blend. The real morphology has been measured using electron tomography to reconstruct the mesoporous TiO

. The geometry was inserted into a mesher and used to solve a drift-diffusion model using finite element method. The simulation is used to cast light over morphology effects in solid state dye solar cells.
