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…
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…
