Sunlight simulation in investigating characteristics of small-size sunlight concentrators and multijunction solar cells

Running head: SIMULATION OF SUNLIGHT TRANSPORT IN SOLAR TREES 1 Monte Carlo Simulation of Sunlight Transport through Solar Trees – a New Paradigm for Improving Sunlight Capture Efficiency

Solar photovoltaic (PV) cells arranged in complex 3D leaf-like configurations—referred to as a solar tree—can potentially collect more sunlight than traditionally used flat configurations. It is hypothesized that this could be because of two reasons. First, the 3D space can be utilized to increase the overall surface area over which the sunlight may be captured. Second, as opposed to traditiona...

Sunlight-thin nanophotonic monocrystalline silicon solar cells

Introducing nanophotonics into photovoltaics sets the path for scaling down the surface texture of crystalline-silicon solar cells from themicroto the nanoscale, allowing to further boost the photon absorptionwhile reducing siliconmaterial loss. However, keeping excellent electrical performance has proven to be very challenging, as the absorber is damaged by the nanotexturing and the sensitivit...

Sunlight therapy and solar architecture.

At the present time sunbathing is being actively discouraged by medical authorities,1 yet little more than fifty years ago it was quite common for sunlight to be prescribed in the treatment of tuberculosis and other diseases. During the First World War sunlight therapy or, as it became known, heliotherapy was used to heal the wounds of casualties on both sides of the conflict; and in the years ...

Type II GaSb quantum ring solar cells under concentrated sunlight.

A type II GaSb quantum ring solar cell is fabricated and measured under the concentrated sunlight. The external quantum efficiency confirms the extended absorption from the quantum rings at long wavelength coinciding with the photoluminescence results. The short-circuit current of the quantum ring devices is 5.1% to 9.9% more than the GaAs reference's under various concentrations. While the qua...
