The interesting case of a single-junction solar cell in outer space
Ido Frenkel, Avi Niv
An isolated single-junction solar cell's temperature in outer space depends only on its radiation exchange with its environment. We consider a cell with zero emissivity below its b…
A unified approach to the thermodynamics of a photovoltaic system
Ido Frenkel, Avi Niv
Thermodynamics is accepted as a universal truth, encompassing all macroscopic objects. Therefore, it is surprising to find that, within our current understanding, the photovoltaic…
Diffusive external light-trap for solar cells
Ido Frenkel, Shilpi Shital, Avi Niv
The ability to absorb light is indispensable for high efficient solar power generation. This places conflicting requirements on the structure of a solar cell: On one hand, it needs…
Second-harmonic generation due to coulomb-like interaction in a heterodimer of subwavelength dimensions
Maya H. Shor1, Esti Toledo, Shilpi Shital +4
We experimentally study the optical second harmonic generation (SHG) from deep subwavelength gold-silver heterodimer and silver-silver and gold-gold homodimers. Our results show th…
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…
