Derived optical constants


A MAPI film was deposited onto a silicon wafer using a two-step vapour reaction phase process and a variable-angle ellipsometer used to take amplitude and phase change measurements. The refractive index and extinction coefficient was extracted from a multi-oscillator model fit to the ellipsometry data, as a function of wavelength, from 300 to 1500 nm

Methylammonium lead iodide, CH3NH3PbI3 (MAPbI3)

Methylammonium lead iodide (CH3NH3PbI3) is a prominent perovskite material used extensively in solar cell technology. It is renowned for its high photovoltaic efficiency due to its optimal band gap and strong light absorption capabilities. This compound typically forms a tetragonal crystalline structure that facilitates efficient charge transport, critical for its application in perovskite solar cells. Its optical properties, particularly its refractive index, are crucial for enhancing light-harvesting efficiency.

Despite its potential in renewable energy applications, CH3NH3PbI3 faces challenges related to environmental impact and stability, given its lead content and sensitivity to moisture and temperature.
