Plasmonic Solar Cells, a New Way to Enhance Energy Conversion Efficiency: Analysis and Modeling of Effect of Metal Geometry

In this article, the effect of plasmonic properties of metal nanoparticles with different shapes, and moreover, their plasmonic-photonic interaction, on solar cell performance were investigated and simulated. Because of low conversion efficiency and then high cost of solar cells, it is difficult to commercialize and replace them with conventional energy resources. But in recent years, the plasm...

A Multi-Objective Programming to Increase Labor Efficiency of a Truck Hub: A Case Study

The problem of staff scheduling at a truck hub for loading and stripping of the trucks is an important and difficult problem to optimize the labor efficiency and cost. The trucks enter the hub at different hours a day, in different known time schedules and operating hours. In this paper, we propose a goal programming to maximize the labor efficiency via minimizing the allocation cost. The propo...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Diffractive Axicons to Increase the Efficiency of Solar Cells

We propose to integrate diffractive axicons into solar cells as a light trap for increasing of light absorbing efficiency. Experimental work and numerical simulations are provided in this paper. The experimental measurements of light-to-electricity conversion efficiency are conducted using a laser with tunable wavelength.
