Methylammonium lead triiodide perovskite-based solar cells efficiency: Insight from experimental and simulation.

This work deals with the growth investigation of the methylammonium lead triiodide (MAPbI) thin films prepared by the spin coating technique. Firstly, MAPbI films were studied by X-ray diffraction (XRD) and scanning electron microscopy (SEM) and UV-Visible spectroscopy as well as photoluminescence techniques are used to calculate the band gap energy. Indeed, the high-quality MAPbI perovskite films were obtained by using Chlorobenzene as an antisolvent with good crystallinity, large grain sizes, and higher absorption compared to MAPbI treated by toluene.

Gallbladder adenomyomatosis: Diagnosis and management.

Introduction: Gallbladder adenomyomatosis is a benign acquired gallbladder disease. It can mimic cancer on radiological findings, leading to a diagnostic dilemma. The management and prognosis of these two gallbladder anomalies are entirely different.
