Electrochemical impedance spectroscopy analysis of hole transporting material free mesoporous and planar perovskite solar cells

Abdulrahim, S.M.; Abdulrahim, Sumayya M.; Ahmad, Zubair; Bahadra, Jolly; Al-Thani, Noora J. ( MDPI , 2020 , Article Review)

The future photovoltaic technologies based on perovskite materials are aimed to build low tech, truly economical, easily fabricated, broadly deployable, and trustworthy solar cells. Hole transport material (HTM) free ...

Performance optimization of CH3NH3Pb(I1-xBrx)3 based perovskite solar cells by comparing different ETL materials through conduction band offset engineering

Ayyaz, Ahmed; Riaz, Kashif; Mehmood, Haris; Tauqeer, Tauseef; Ahmad, Zubair ( Elsevier , 2020 , Article)

Numerical simulations can provide the physical insights into the carrier transport mechanism in the solar cells, and the factors influencing their performance. In this paper, perovskite solar cell (PSC) based on the mixed ...

Long-Term Stability Analysis of 3D and 2D/3D Hybrid Perovskite Solar Cells Using Electrochemical Impedance Spectroscopy

Abdulrahim, Sumayya M.; Ahmad, Zubair; Bhadra, Jolly; Al-Thani, Noora Jabor ( MDPI , 2020 , Article)

Despite the remarkable progress in perovskite solar cells (PSCs), their instability and rapid degradation over time still restrict their commercialization. A 2D capping layer has been proved to overcome the stability issues; ...

Detection of voltage pulse width effect on charge accumulation in PSCs using EFISHG measurement

Zubair, Ahmad; Taguchi, D.; Paek, Sanghyun; Mishra, Arti; Bhadra, Jolly; ... more authors ... less authors ( Elsevier , 2020 , Article)

We report the effect of applied pulse width on charge accumulation in triple cation perovskite solar cells (PSCs) during the Electric Field Induced Second Harmonic Generation (EFISHG) measurements. The PSCs were prepared ...

Metal halide-based photodetector using one-dimensional MAPbI3 micro rods

Raza, Ehsan; Ahmad, Zubair; Mishra, Arti; Aziz, Fakhra ( Springer , 2020 , Article)

In the present work, we report the fabrication of a photodetector using methylammonium lead iodide perovskite (MAPbI3) micro rod. Photosensitivity of the Ag/MAPbI3/Ag photodetector has been studied under various light ...
