We present a study on the structure and dynamics of poly (ethyl methacrylate) (PEMA), one of the polymers with shortest side-group in the poly (n -alkyl methacrylate)s (PnMAs) series. The ...

Surface passivation of perovskite grains is one of the promising methods to reduce recombination and improve stability of perovskite solar cells (PSCs). We herein report the effect of a melaminium ...
