Double-absorber thin-film solar cell with 34% efficiency
Faiz Ahamd, Akhlesh Lakhtakia, Peter B. Monk
Power-conversion efficiency is a critical factor for the wider adoption of solar-cell modules. Thin-film solar cells are cheap and easy to manufacture, but their efficiencies are l…
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…
Optoelectronic optimization of graded-bandgap thin-film AlGaAs solar cells
Faiz Ahmad, Akhlesh Lakhtakia, Peter B. Monk
An optoelectronic optimization was carried out for an AlGaAs solar cell containing (i) an n-AlGaAs absorber layer with a graded bandgap and (ii) a periodically corrugated Ag backre…
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…
