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…
Radial deformation measurements of isolated pairs of single-walled carbon nanotubes
Z. R. Abrams, Y. Hanein
Interactions between atoms of bound single-walled carbon nanotubes (SWNTs) are known to cause measurable distortion to the tube's original circular cross-section frame. High-resolu…
Tube-Tube and Tube-Surface Interactions in Straight Suspended Carbon Nanotube Structures
Z. R. Abrams, Y. Hanein
An investigation concerning the tautness of suspended carbon nanotubes (CNTs), grown using the chemical vapor deposition (CVD) method is presented. The suspended nanotubes were ana…
