Abstract

Methylammonium lead iodide is a material with a broad absorption spectrum and interesting emission properties as well as defect physics. Defects in the absorber layer have different activation energy. So, keeping in mind the difference in behavior at different wavelengths corresponding to a different energy, the performance of the n-i-p structured devices along with frequency and voltage-dependent capacitive behavior variation were analyzed at the different parts of the solar spectrum. The difference in charge carrier generation, extraction, and accumulation have been observed for the devices with varying wavelengths. A brief overview of the photoluminescence behavior has also been obtained from excitation wavelength varying experiments.
