In March, a meeting was held by the Japan Society of Applied this meeting a research group from the Kyoto Institute of Technology talked about their new photovoltaic cell that is capable of generating electricity not only from visible light, but from ultraviolet and infrared .
Figure also shows the cell structure of the retina including the light-sensitive rod cells and cone cells. Also shown are the ganglion cells and nerve fibers that transmit the visual information to the brain. Rod cells are more abundant and more light sensitive than cone cells. Rods are sensitive over the entire visible spectrum. Human Eyes W.

A very large array of solar cells on each satellite would provide electricity, which would be converted to microwave energy and beamed to a receiving antenna on the ground.
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible is therefore generally invisible to the human eye, although IR at wavelengths up to nanometers (nm)s from specially pulsed lasers can be seen by humans under certain conditions. IR wavelengths extend from the nominal red edge . so far the possibility to supply power to e.g. he-licopters, baloon-based platforms, experimental air-planes, experimental cars, rovers and cell phones. The rst experiment was conducted by W. Brown in , when also the rst \rectenna"xxand invented xxA rectenna is a power conversion device from converting mi-crowave to DC.

An analytical investigation is performed to assess the feasibility of long-wavelength power converters for the direct conversion of IR radiation onto electrical power.

Summers. In the satellite power system (SPS), satellites in geosynchronous earth orbit would collect solar energy in space, convert it to microwaves, and transmit the microwaves to receiving antennas. A 1 GW SPS power plant has the following typical dimensions. The area of a solar cell panel is approximately 10 km2 (2km x 5km) for production of 2GW DC power with the solar cell conversion efficiency of 15%.
The transmitting antenna array will typically be 1km in Size: 1MB.

SOLAR POWER SATELLITE (SPS) SYSTEM Solar Energy Conversion - Solar Photons to DC Two basic methods of converting sunlight to electricity have been studied: photovoltaic (PV) conversion, and solar dynamic (SD) conversion. Most analyses of solar power satellites have focused on photovoltaic conversion (commonly known as “solar cells”).

Infrared Plastic Solar Cell Scientists have invented a plastic solar cell that can turn the suns power into electric energy even on a cloudy day.
Plastic solar cells are not existing materials are only able to harness the sun’s visible light. Infrared control signals from your remote can’t pass through solid objects like wooden cabinet doors or walls, but with a remote control extender, you can install DVD and Blu-Ray players, stereo receivers, and other equipment out of sight and still use your remotes normally.

ABSTRACT This paper reports on the futuristic advances in power transmission through microwaves. Sun is a limitless source of energy. A space power satellite (sps) orbiting round the earth traps solar energy and generates electric power using photovoltaic cells of sizable area.
Photovoltaic Systems and Applications 23 Moreover, such variety in technology is needed to enhance the deployment of solar energy for a greener and cleaner environment.
Devices such as space PV cell technology were also described and the progress in this field is expanding. In addition, the applications of PV installations are described. Fig. Of all the many spaceflight concepts NASA has studied, the most enormous was the Solar Power Satellite (SPS) fleet.
Czech-born physicist/engineer Peter Glaser outlined the concept in a brief article in the esteemed journal Science in Novemberand was awarded a patent for his invention on Christmas Day.
