Morphology Analysis of Lead Iodide- And Lead Acetate based Perovskite Layers for Solar Cell Application
Morphology Analysis of Lead Iodide- And Lead Acetate based Perovskite Layers for Solar Cell Application. ABSTRACT Organolead trihalide perovskite solar cells have shown success as light absorbers in photovoltaic cells due to their efficiency increasing from 3.5% to over 20% within only five years. However, pinhole formation and incomplete coverage of solution-processed perovskite film results in increased current leakage, reducing efficiency. […]
Substitutional and Vacancy defects in Two-dimensional ALSB: a First Principle Approach
Substitutional and Vacancy defects in Two-dimensional ALSB: a First Principle Approach. ABSTRACT AlSb is a semiconductor material that exists in 3D as well as 2D regimes. also have high electron mobility which is useful for application in high-speed electronic devices. AlSb has potential applications in radiation detection. Defects, including intrinsic and extrinsic have been shown […]
Numerical Modeling of Wellbore Instability (Tensile Failure) Using Fracture Mechanics Approach
Numerical Modeling of Wellbore Instability (Tensile Failure) Using Fracture Mechanics Approach. ABSTRACT When a well is drilled, the equilibrium in-situ stress is changed. In order to support the stress relief induced by the drilling and to prevent hydrocarbon influx into the cavity, the borehole is filled with a fluid. These operations create new stress configurations. […]
Investigation of Cement Mortar and Steel Used in Reinforced Concrete in Nigeria
Investigation of Cement Mortar and Steel Used in Reinforced Concrete in Nigeria. ABSTRACT “INVESTIGATION OF CEMENT MORTAR AND STEEL USED IN REINFORCED CONCRETE IN NIGERIA” The study explores the investigation of the chemical composition, microstructure and mechanical properties of steel and cement mortar used in reinforced concrete. The compositions and mechanical properties of the locally […]
Effect of Annealing Temperature on the Formation of Methylammonium Tin Tri-Iodide Perovskite Thin Film
Effect of Annealing Temperature on the Formation of Methylammonium Tin Tri-Iodide Perovskite Thin Film. ABSTRACT Organic-inorganic perovskite photovoltaics (PVs) have attracted a lot of attention as high-efficiency thin-film PVs which are relatively cheap and easy to fabricate. Lead halide perovskites have shown a rapid rise in power conversion efficiency by 3.8 % in 2009 to […]
The Effect of Bitumen Coatings on the Corrosion of Low Carbon Steels (Api 5l X65)
The Effect of Bitumen Coatings on the Corrosion of Low Carbon Steels (Api 5l X65). ABSTRACT The corrosion behavior of uncoated and cut-back bitumen coated X65 Steel samples are being investigated in environments of different pH (2, 3, 4 and 7). Immersion tests were carried out on the samples at 25ºC. The comparison of the […]
Phytoremediation of Crude Oil Contaminated Soil using Cowpea and Indole-3-Acetic Acid as A Growth Hormone
Phytoremediation of Crude Oil Contaminated Soil using Cowpea and Indole-3-Acetic Acid as A Growth Hormone. ABSTRACT One of the unintended impacts of crude oil exploration is the pollution of agricultural land and aquatic resources when there is accidental oil spillage. The environmental effect of this has resulted in untold hardship to communities within oil producing […]
Adhesion and Optoelectronic Properties of Organic Light Emitting Devices (Oleds) and Hybrid Organic-inorganic Light Emitting Devices (Hoileds) with Tio2 Nano-particles
Adhesion and Optoelectronic Properties of Organic Light Emitting Devices (Oleds) and Hybrid Organic-inorganic Light Emitting Devices (Hoileds) with Tio2 Nano-particles. ABSTRACT This study examines the basic operation of an Organic Light Emitting Device (OLED) and Hybrid Organic-Inorganic Light Emitting Devices (HOILED) by looking at the individual characteristics of each layer which makes up the entire device. Adhesion […]
Modeling of Cold Welding and Lamination of Organic and Hybrid Organic/Inorganic Structures
Modeling of Cold Welding and Lamination of Organic and Hybrid Organic/Inorganic Structures. ABSTRACT This research work presents the results of analytical studies of effects of pressure and adhesion energy on the interfacial properties of cold welded and laminated surfaces in organic and Hybrid Organic/Inorganic electronic structures. The analytical modeling is based on the physics of elastic behaviour of […]
