Zinc oxide nanowire arrays for silicon core/shell solar cells.
The optics of core / shell nanowire solar cells was investigated. The optical wave propagation was studied by finite difference time domain simulations using realistic interface morphologies. TheExpand

Comparison of Light Trapping in Silicon Nanowire and Surface Textured Thin-Film Solar Cells
The optics of axial silicon nanowire solar cells is investigated and compared to silicon thin-film solar cells with textured contact layers. The quantum efficiency and short circuit current densityExpand

Color Sensing by Optical Antennas: Approaching the Quantum Efficiency Limit
Color image sensing is commonly carried out by an array of color pixels. Each of the color pixels consists of at least three sensing elements in combination with optical filters for red, green and ...

Short Gamma Ray Bursts and their Afterglow Signatures in Dense Stellar Systems
The hypothesis that short GRBs arise from the coalescence of binary compact stars has recently gained support. With this comes the expectation that the afterglow should bear the characteristicExpand

Combining photosynthesis and photovoltaics: A hybrid energy harvesting system using optical antennas.
A hybrid energy harvesting system is proposed which combines photosynthesis and photovoltaics. First the light passes through a spectrally selective solar cell, which absorbs almost all green light,Expand
