Journal ArticleDOI
Structural, electronic and optical properties of Ag2MgSn(S/Se)4 quaternary chalcogenides as solar cell absorber layer: An Ab-initio study
A. Srivastava,Paramita Sarkar,Susanta Kumar Tripathy,Trupti Ranjan Lenka,P. S. Menon,Fen Lin,Armin G. Aberle +6 more
TL;DR: In this paper, generalized gradient approximation (GGA) and the Heyd-Scuseria-Ernzerhof (HSE) hybrid functional within the framework of density functional theory (DFT) are used to investigate the structural, electronic and optical properties of Ag2MgSn(S/Se)4 quaternary chalcogenides in kesterite and stannite phases.
Journal ArticleDOI
Electronic Structure and Optical Properties of Gallium-DopedHybrid Organic–Inorganic Lead Perovskites from First-PrinciplesCalculations and Spectroscopic Limited Maximum Efficiencies
TL;DR: In this article, the hybrid organic-inorganic lead perovskites have brought a revolution among the solar cell researchers never seen before, and low cost and ultra-high power conversion efficiencies of the hybrid OI-INO perovskiy hybrid solar cells have been achieved.
Journal ArticleDOI
Impact of Sn doping on methylammonium lead chloride perovskite: An experimental study
Paramita Sarkar,A. Srivastava,Susanta Kumar Tripathy,Krishna Lal Baishnab,Trupti Ranjan Lenka,P. S. Menon,Fen Lin,Armin G. Aberle +7 more
TL;DR: In this article, the improved crystallinity and enhanced absorption edge toward longer wavelength are observed due to the increased amount of tin (Sn) in the Pb site of CH3NH3PbCl3.
Journal ArticleDOI
Exploring the effect of Ga3+ doping on structural, electronic and optical properties of CH3NH3PbCl3 perovskites: an experimental study
Paramita Sarkar,A. Srivastava,Susanta Kumar Tripathy,Krishna Lal Baishnab,Trupti Ranjan Lenka,P. S. Menon,Fen Lin,Armin G. Aberle +7 more
TL;DR: In this paper, Ga-doped CH3NH3PbCl3 perovskites were analyzed for their structural, optical, morphological, elemental, and electronic properties using X-ray powder diffraction (XRD), UV-Vis diffuse reflectance spectroscopy (UV-Vis-DRS), field emission gun-scanning electron microscopy (FEG-SEM), energy-dispersive spectrograph (EDS), and photoluminescence spectrographic (PL), respectively.
