Modal formulation for diffraction by absorbing photonic crystal slabs
Kokou B. Dossou, Lindsay C. Botten, Ara A. Asatryan +5
A finite element-based modal formulation of diffraction of a plane wave by an absorbing photonic crystal slab of arbitrary geometry is developed for photovoltaic applications. The…
Total absorption of visible light in ultra-thin weakly-absorbing semiconductor gratings
Björn C. P. Sturmberg, Teck K. Chong, Duk-Yong Choi +7
The perfect absorption of light in subwavelength thickness layers generally relies on exotic materials, metamaterials or thick metallic gratings. Here we demonstrate that total lig…
Optimizing Photovoltaic Charge Generation of Nanowire Arrays: A Simple Semi-Analytic Approach
Björn C. P. Sturmberg, Kokou B. Dossou, Lindsay C. Botten +4
Nanowire arrays exhibit efficient light coupling and strong light trapping, making them well suited to solar cell applications. The processes that contribute to their absorption ar…
Absorption enhancing proximity effects in aperiodic nanowire arrays
Björn C. P. Sturmberg, Kokou B. Dossou, Lindsay C. Botten +4
Aperiodic Nanowire (NW) arrays have higher absorption than equivalent periodic arrays, making them of interest for photovoltaic applications. An inevitable property of aperiodic ar…
Nanowire array photovoltaics: Radial disorder versus design for optimal efficiency
Björn C. P. Sturmberg, Kokou B. Dossou, Lindsay C. Botten +4
Solar cell designs based on disordered nanostructures tend to have higher efficiencies than structures with uniform absorbers, though the reason is poorly understood. To resolve th…
Double-heterostructure cavities: from theory to design
Sahand Mahmoodian, J. E. Sipe, Christopher G. Poulton +4
We derive a frequency-domain-based approach for radiation (FAR) from double-heterostructure cavity (DHC) modes. We use this to compute the quality factors and radiation patterns of…
