Enhanced optical properties of perovskite thin film through material optimization for photovoltaic application

Abstract

The optical performance of the perovskite materials is enhanced through material optimization. This work seeks to establish the role of antisolvent and additive with new material composition on light absorption property. Due to this composition we extended the wavelengths to near Infrared range which is a suitable property for photovoltaic device. From the features of the film, optical parameters, together with anti-stoke shift and dielectric constant were calculated using Cauchy dispersion formalism. Based on our results, dielectric constant which is considered as a design parameter for photovoltaic cell and an unusual anti-stoke shift were observed. In sum, the optical properties are tied to material composition, morphology and technique used.

Hybrid Perovskite Thin Film

“…From our work [8,11], the annealing temperature had strong impact on the formation of perovskite. The under-and over-annealing were both detrimental to cell performance.…”

“…Olaleru et al recorded that dropping ethyl acetate on a perovskite precursor film during the spinning process caused a homogenous perovskite film with good reproducibility [11]. Cohen et al investigated the relationship between anti-solvent (toluene) treatment and electronic properties of the perovskite films together with surface morphology [9].…”

First-principles calculations investigating structural, electronic optical and elastic properties of ABSe3 (A = Rb, Cs) compounds explored for photovoltaic and optoelectronics applications

“…Material optimization is based on the quality of the material through the potential coupling of its optical properties with its different properties such as electronic, magnetic and thermal. Within a few years, the great challenge for researchers is on searching and giving new hope for stable materials with superb electronic and optical properties which can thus be considered as key in the design of photovoltaic and optoelectronic devices [1] and achieve a great photovoltaic performance. Additionally, perovskite materials has become the most promising materials in the world and the best candidate for the future in the field of photovoltaic's industry [2] and also other optoelectronics devices due to the considerable efforts made by the researchers, to their easy fabrication and also their excellent optoelectronic characteristics, such as small exciting binding energy, appropriate band gap, great light absorption, and long exciting diffusion length [3].…”
