Modeling the optoelectronic properties of quantum dot-based perovskite structure for efficient solar cell

The present research presents the efficiency of quantum dot-based perovskite solar cell with the help of Finite element methods.The proposed structure is made up lead sulphide (PbS)-based colloidal quantum dot structure, where PbS-based ethanol layer plays a vital role. The novelty of the proposed structure is that the proposed solar cell device is suitable for both visible and IR signals. The principle of investigation of efficiency relies on the reflectance and transmittance of the signal, where absorbance is a function of reflectance and transmittance. The amount of the absorbance pertaining to the proposed structure decides the amount of generation of electron–hole pairs of electrons. The outcome of the present research indicates that the efficiency of the generation of electron–hole pair by the quantum-based perovskite structure is more than 96%(varies from 96 to 100%) with respect to the visible signal, where the same efficiency is calculated as 100% for an entire infrared region.
