The Extreme Science and Engineering Discovery Environment helps advance Green Energy Solar Power technologies

XSEDE super computing networked clusterPractical solutions capable of fully utilizing Solar Energy Green Design is our future. The new achievements in high performance computing such as XSEDE networked cluster, help practical resolution of the solar dilemmas, would it be for the open space macro solar installations, or for the micro solar powered GPS naviagtor devices. The Fresnel lens entered the solar electricity sector as a viable alternative just recently. The new polymers for thin film solar cells of new  micro-miniature devices are also in its infantry. The new solar technologies for macro and micro worlds are constantly evolving, and there is no single dominant design.

In the open field solar installations it is possible to concentrate solar energy using lenses, most often the Fresnel lenses. Lenses allow 500 times increase of solar density on the Concentrated PhotoVoltaic, or CPV technology, the solar-electric generator cells. The CPV design is based on gallium cells with triple junction. This complex but robust and reliable technology have  been tried and widely used in open space by GPS constellation and other satellites and spacecraft vehicles. 

Innovation - Thin Film Solar Cells

The traditional silicon solar cells cannot stand the heat in the focus tip of Fresnel lenses. The gallium cells with triple junction CPV technology stand strong in high temperature. Sunlight can be concentrated on the cells to improve efficiency up to forty percent. With associated installation and technology conversion losses the practical efficiency improvement is 25%. Concentrating light for PhotoVoltaic cells requires direct sunlight rather than diffuse light. Fresnel lens works in clear, sunny locations, and often tracking is required for the macro solar installations.


In the micro world of solar applications palm size portable device has no luxury of virtually unlimited open surface available for satellite in the open space. Traditional AAA or Li-ion batteries dominant power source for most portable communicators, GPS handheld navigators and smartphones. As information provided to mobile user by her or his portable communicator or wristwatch GPS navigator, or wearable personal trainer - the personal health status adviser, collecting and processing critical health pulses from heart beat monitor and other sensors is priceless.

Especially in the remote inhabitat, outer terrain, where the personal communicator, GPS navigator and wearable computing center adviser comprise the survival kit for warrior, traveler, scientist, researcher, nature explorer. Solar cells need be open to sunshine, and coexist with personal communicator antenna array of GPS quad helix antenna, GPS ceramic patch antenna, radio network antenna,  Bluetooth and WiFi antennas. Antenna array cannot be blocked by the solar cell array, therefore solar cell array and antenna array are placed side by side, often as separate units.


TGreen Energy Solar o make a new step towards Green Energy Solar power technology breakthrough researchers and scientists use newest supercomputer clusters, such as the XSEDE network, to research solar energy, help identify new materials to be used in lenses and solar cells, and to further improve their efficiency lowering associated costs. XSEDE networked cluster of supercomputers represents the newest Extreme Science and Engineering Discovery Environment. the XSEDE networked cluster performs calculations, measured in supercomputing units, that are beyond the capabilities of regular computational platforms. 

The quantum electromechanical computations that took weeks to solve on a mainframe now, with access to XSEDE, take only hours of XSEDE supercomputing units to solve. The supercomputing cluster allowed researchers to discover new polymer structures with unique sun light transformation qualities. Similarly computations for the new configurations of the complex quad helix and other transmission rich radio frequency separation of intersecting cross-influence bands for the microelectronic element arrays allow increase the density of micro miniature integrated environments and reduce the interference. The new XSEDE assisted discoveries simplify the process of solar cells construction and reduce the environmental impact of manufacturing.
