Simulation of solid-state dye solar cells based on organic and perovskite sensitizers

In this work we present a multiscale numerical simulation of solid-state Dye and Perovskite Solar Cells where the real morphology of the mesoporous active layer is taken into account. Band alignment and current densities are computed using the drift-diffusion model. In the case of Dye cells, a portion of the real interface is merged between two regions described using the effective medium approximation, casting light on the role of trapped states at the interface between TiO2 / Dye / hole transporting materials. A second case of study is the simulation of Perovskite Solar Cell where the performances of cells based on Alumina and Titania mesoporous layer are compared. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
