Perovskite solar cells [1] are emerging as a leading technology in the landscape of thin film solar cells. They have numerous advantages compared to other technologies as they have an excellent light absorption, low recombination rate and high open circuit voltage. Moreover, the possibility to grow the film of perovskite using different processes, from evaporation to solution process, opens relevant perspectives on the possible application of this technology.
An interesting question has been rised concerning the influence of trap states at the TiO2/Perovskite interface and the consequent charge accumulation [2]. In order to investigate this problem we have developed a simulation tool [3], based on drift-diffusion, that allows to compute the complete JV characteristics of the device including the real mesoporous morphology in 3D. This will cast light on the effects of interface and mesoporous morphology on the overall performance of the device.
