Abstract: (613 Views)
Nowadays perovskite nano materials due to unique optical properties attract sighnificant interest. Amongst the factors affecting the performance of perovskite films is the morphology of perovskite layers. One of the factores influencing the morphology of perovskite layers is thickness. In this paper, the effect of velocity change in the second stage of two-stage coating on the thickness and surface morphology of perovskite film was investigated. The result is that the perovskite created by the first velocity of 1000 rpm/s and second velocity of 5000 rpm/s in compared to other cases, has a crystal structure with minimum effect and a high intensity of photoluminescence spectrum.
