Towards highly efficient thin-film solar cells with a graded-bandgap CZTSSe layer
Faiz Ahmad, Akhlesh Lakhtakia, Tom H. Anderson +1
A coupled optoelectronic model was implemented along with the differential evolution algorithm to assess the efficacy of grading the bandgap of the CZTSSe layer for enhancing the p…
Efficiency enhancement of ultrathin CIGS solar cells by optimal bandgap grading
Faiz Ahmad, Tom H. Anderson, Peter B. Monk +1
The power conversion efficiency of an ultrathin CIGS solar cell was maximized using a coupled optoelectronic model to determine the optimal bandgap grading of the nonhomogeneous CI…
Coupled Optoelectronic Simulation and Optimization of Thin-Film Photovoltaic Solar Cells
Tom H. Anderson, Benjamin J. Civiletti, Peter Monk +1
A design tool was formulated for optimizing the efficiency of inorganic, thin-film, photovoltaic solar cells. The solar cell can have multiple semiconductor layers in addition to a…
Optimization of nonhomogeneous indium-gallium-nitride Schottky-barrier thin-film solar cells
Tom H. Anderson, Akhlesh Lakhtakia, Peter B. Monk
A two-dimensional model was developed to simulate the optoelectronic characteristics of indium-gallium-nitride (InGaN), thin-film, Schottky-barrier solar cells. The solar cells com…
Optimization approach for optical absorption in three-dimensional structures including solar cells
Benjamin J. Civiletti, Tom H. Anderson, Faiz Ahmad +2
The rigorous coupled-wave approach (RCWA) and the differential evolution algorithm (DEA) were coupled in a practicable approach to maximize absorption in optical structures with th…
On optical-absorption peaks in a nonhomogeneous thin-film solar cell with a two-dimensional periodically corrugated metallic backreflector
Faiz Ahmad, Tom H. Anderson, Benjamin J. Civiletti +2
The rigorous coupled wave approach (RCWA) was implemented to investigate optical absorption in a triple-p-i-n-junction amorphous-silicon solar cell with a 2D metallic periodically…
A simple construction for a cylindrical cloak via inverse homogenization
Tom H. Anderson, Tom G. Mackay, Akhlesh Lakhtakia
An effective cylindrical cloak may be conceptualized as an assembly of adjacent local neighbourhoods, each of which is made from a homogenized composite material (HCM). The HCM is…
Ray trajectories for Alcubierre spacetime
Tom H. Anderson, Tom G. Mackay, Akhlesh Lakhtakia
The Alcubierre spacetime was simulated by means of a Tamm medium which is asymptotically identical to vacuum and has constitutive parameters which are ontinuous functions of the sp…
Ray trajectories for a spinning cosmic string and a manifestation of self-cloaking
Tom H. Anderson, Tom G. Mackay, Akhlesh Lakhtakia
A study of ray trajectories was undertaken for the Tamm medium which represents the spacetime of a cosmic spinning string, under the geometric-optics approximation. Our numerical s…
