Journal ArticleDOI
Instability in CH3NH3PbI3 perovskite solar cells due to elemental migration and chemical composition changes.
Zubair Ahmad,Mansoor Ani Najeeb,Rana Abdul Shakoor,Abdulla Alashraf,Shaheen A. Al-Muhtaseb,Ahmed Soliman,Mohammad Khaja Nazeeruddin +6 more
TL;DR: X-ray photoelectron spectroscopy has been used to investigate the compositional changes caused by device degradation over the period of 1000 hrs and confirms the migration of metallic ions from the bottom electrode (ITO) as a key factor causing the chemical composition change in the perovskite layer besides the diffusion of oxygen.
Journal ArticleDOI
Nanostructured chromium-based broadband absorbers and emitters to realize thermally stable solar thermophotovoltaic systems.
Muhammad Aamir Abbas,Joohoon Kim,Ahsan Sarwar Rana,In-Cheol Kim,Bacha Rehman,Zubair Ahmad,Y. Massoud,Junhwa Seong,Trevon Badloe,Keun Woo Park,Muhammad Qasim Mehmood,Muhammad Zubair,Junsuk Rho +12 more
TL;DR: In this article , a wideband thermophotovoltaics (STPV) system consisting of an absorber and an emitter pair achieving high absorptance of solar radiation within the range of 400-1500 nm (covering the visible and infrared regions), whereas the emitter achieves an emittance of >95% at a wavelength of 2.3 μm.
Journal ArticleDOI
Performance optimization of CH3NH3Pb(I1-xBrx)3 based perovskite solar cells by comparing different ETL materials through conduction band offset engineering
TL;DR: In this article, a perovskite solar cell (PSC) based on the mixed perov-skite (CH3NH3Pb(I1-xBrx)3/Spiro-OMeTAD/Au) was numerically simulated using the SCAPS simulator.
Journal ArticleDOI
Facile preparation of N-S co-doped graphene quantum dots (GQDs) from graphite waste for efficient humidity sensing
Khouloud Jlassi,Shoaib Mallick,Abubaker Eribi,Mohamed M. Chehimi,Zubair Ahmad,Farid Touati,Igor Krupa +6 more
TL;DR: In this article, GQDs (10´mg/ml) based impedance sensors were evaluated for the potential application for resistive humidity sensors, which showed good sensitivity and lowered hysteresis as compared to the other ratios (2.5, 5´mg, and 10´mg) of the GQD.
Journal ArticleDOI
Synthesis and properties of polyelectrolyte multilayered microcapsules reinforced smart coatings
Adnan Khan,Adnan Khan,Fareeha Ubaid,Eman M. Fayyad,Zubair Ahmad,Rana Abdul Shakoor,Maria de Fátima Montemor,Ramazan Kahraman,Said Mansour,Mohammad K. Hassan,Anwarul Hasan,Aboubakr M. Abdullah +11 more
TL;DR: In this article, the synthesis, characterization and properties of novel polyelectrolyte multilayered microcapsules used as smart additives in organic coatings for corrosion protection of steel parts were investigated.
