Variation of PbS Layer Thickness in Colloidal Quantum Dot Solar Cell
Abstract: The broad tuning of semiconductor band structure is proposed for colloidal quantum dot via the quantum size effect by several workers. In this paper, we define brief details on effect of the thickness of lead sulphide (PbS) layer as the absorbing photovoltaic materials in the colloidal CQD solar cell and show their effect on the performance of the solar cell. The calculated results shows that with lower thickness of 180 …

Inverse Heat Transfer Analysis Applied to Heat Treatment Process
Abstract: Direct measurement of heat flux at the surface of a surface subjected to extreme heat using conventional or traditional methods is an inexpedient task; but it can be estimated by an inverse analysis utilizing transient temperature recordings taken at specific location beneath the heated surface. The problem on Inverse Heat Transfer (IHT) depends upon the heat flux and various temperature measurements for the approximation of variable quantities appearing in the …

Performance Analysis of Shell and Tube Heat Exchanger using Engineering Equation Solver
Abstract: The following paper consists of extensive thermal analysis of the performance of Shell and tube heat exchanger under various configurations. To serve the purpose a simplified model of shell and tube heat exchanger has been designed using kern’s method to cool the water from 55°C to 45°C by using water around room temperature. Then we have extrapolated the performance analysis using the EES (Engineering Equation Solver) software to simulate the …
