The charge carrier mobility in halid perovskites is still not fully understood. We have been discussing dielectric effects as one fundamental piece in the explanation of the large screening of defects and the polaron mobility. In this presentation we compare different organic molecules for their influence on the dielectric response. The interrelation of molecule mobility and dielectric screening will be discussed.
Keywords: charge carrier mobility; halide perovskites; dielectric effects
