Electromagnetic approach to ultrathin solar cell efficiencies
A. Niv, M. Gharghi, Z. R. Abrams +2
Current methods for evaluating solar cell efficiencies cannot be applied to extremely thin cells where phenomena from the realm of near field optics prevail. We overcome this probl…
Theoretical Efficiency Comparison between Carrier Multiplication and Down-Conversion 3rd Generation Solar Cell Designs
Z. R. Abrams, A. Niv, C. Gladden +2
Methods of exceeding the detailed balance limit for a single junction solar cell have included down-converting high energy photons to produce two photons; and carrier multiplicatio…
A Carpet Cloak Device for Visible Light
Majid Gharghi, Christopher Gladden, Thomas Zentgraf +4
We report an invisibility carpet cloak device, which is capable of making an object undetectable by visible light. The cloak is designed using quasi conformal mapping and is fabric…
Deep Subwavelength Plasmonic Lasers
Rupert F Oulton, Volker J Sorger, Thomas Zentgraf +5
Laser science has tackled physical limitations to achieve higher power, faster and smaller light sources. The quest for ultra-compact laser that can directly generate coherent opti…
