 The proposed structure consists of a monolayer MOS2 film sandwiched between two layers of CH3-NH3-PBI3 perovskite. By adjusting the number of periods, the absorbance, transmittance, and reflectance coefficients can be controlled. For incident light in the visible spectrum, the absorbance coefficient increases with increasing period number, while for infrared light, the absorbance coefficient decreases with increasing period number. This structure could be used for applications such as improving the efficiency of solar cells and infrared sensors. This article was authored by Fahad Sattri and Sogra Mureshadi.
