Effects of Bending and Stretching on Hybrid Organic-Inorganic Trihalide Perovskite Solar Cells
(2014-12-15)
In the recent decade, hybrid organic- inorganic trihalide perovskite solar cells have attracted significant interest from the scientific community due to their unique optoelectrical properties, ease and low cost of ...
Limiting Efficiency of Perovskite Solar Cells
(2014-12-15)
The power conversion efficiency of perovskite solar cells has risen from as low as 3.8% to as high as 19.3% in just five years with yet a projected value of over 20% in the next few years by experimentalists. Such a ...
Hydrodynamics Behaviour of Slug Flow in 80 0 off the Horizontal Pipe using Electrical Capacitance Tomography (ECT) Data
(2014-12-12)
This study presents an investigation of the hydrodynamics behaviour of slug flow in an inclined (80 degree inclination) and 67 mm internal diameter pipe. The study provides a more rudimentary explanation into the physical ...
Performance Optimization of Tin Halide Perovskite Solar Cells Via Numerical Simulation
(2014-12-15)
Organic-inorganic hybrid perovskite solar cells have attracted great attention in the photovoltaic research community in recent years due to its ease of processing, low cost of production, superb light-harvesting ...
Integrated Petrophysical Evaluation of Turbiditic Sands in Niger Delta Basin
(2014-12-12)
Large quantities of petroleum resources in the Niger Delta province are confined to unconsolidated turbiditic and silici-clastic rocks. These rocks are usually associated with high volumes of shale. The high volumes of ...
Evaluation of Oil Recovery Efficiency of Water-Flooding, Gas-Flooding and Wag Injection in a Turbidite Reservoir
(2014-12-12)
Worldwide awareness of thin-bedded reservoirs (including turbidites) has become increasingly important with about 30-40% of the world’s oil in-place resources confined within thin-bed laminated reservoirs (Tyagi et al. ...
Enhanced Oil Recovery in High Viscous Reservoir using the Thermal Process
(2014-12-12)
New sources of energy should be found to relieve the high demand of energy. Even though heavy oil and bitumen are difficult to produce due to their high viscosity which can be reduced by heating, with increased oil price, ...
Evaluation of in-fill Well Placement and Optimization Using Experimental Design and Genetic Algorithm
(2014-12-12)
Determination of optimal well locations for infill drilling is a challenging task because engineering and geologic variables affecting reservoir performance are often nonlinearly correlated and have some degree of uncertainty ...
Comparative Economics of Petroleum Production Optimization Techniques
(2014-12-15)
Hydrocarbon production in the petroleum industry is often constrained by reservoir heterogeneity, deliverability and capacity of surface facilities, also optimization technique in the petroleum industry requires execution ...
Mechanistic Models for Predicting Sand Production: a Case Study of Niger Delta Wells
(2014-12-12)
Niger Delta Province is predominantly a friable, unconsolidated sandstone terrain suggesting the expectation of sand production while developing hydrocarbon reserves in such terrain. In this study, a simple and easy-to-use ...
