A perovskite film with an area of 51cm 2 was successfully obtained and was testified to be uniform with optical measurements. The perovskite solar cells (1 cm 2) based on this method achieved an efficiency of 17.6% with high reproducibility which was the highest record for non spin coating methods at that time. More importantly, we recently

The goal of this work is to identify favored pathways for preparation of defect resilient attached wurtzite CdX (X = S, Se, Te) nanocrystals. We seek guidelines for oriented attachment of faceted nanocrystals that are most likely to yield pairs of nanocrystals with either few or no electronic defects or electronic defects that are in and of themselves desirable and stable.

Resume The quality of perovskite films is critical to the performance of perovskite solar cells. However, it is challenging to control the crystallinity and orientation of solution processed perovskite films. Here, we report solution phase Van der Waals epitaxy growth of MAPbI3 perovskite films on MoS2 flakes for the first time.

Abstract. In this paper, two step sequential spin dip and spin spin coating, as well as one step spin coating, methods are used to fabricate methylammonium lead mixed halide perovskites to study the effect of process parameters, including the choice of the solvent, annealing temperature, spin velocity, and dipping time on the characteristics of the perovskite film.
Recently, perovskite solar cells have attracted tremendous attention due to their excellent power conversion efficiency, low cost, simple fabrications, and high photovoltaic performance. Furthermore, the perovskite solar cells are lightweight and possess thin film and semitransparency.
