Researchers develop cool way to improve solar cell efficiency

By Kelly Hodgkins for Digital Trends:    A team of engineers from Stanford University have invented a cool way to improve the performance of solar panel arrays. A new material that the team produced literally will lower the temperature of solar cells even while they are operating in full-strength sunlight. As the solar cells cool, their efficiency will rise, leading to significant gains in the amount of energy harvested from the sun. Solar panel technology has improved by leaps and bounds, but the technology has a flaw that limits the efficiency of the system. The panels must face the sun to operate, but the heat from this exposure diminishes their ability to convert light into energy. The hotter they get, the less efficient they become. This issue has perplexed the industry for years, but the Stanford team may have discovered a material that can help dissipate this excess heat without affecting the operation of the solar array. The solution, proposed by Stanford electrical engineering professor Shanhui Fan, research associate Aaswath P. Raman, and doctoral candidate Linxiao Zhu, uses a material that is able to capture and emit thermal radiation (heat) away from the solar call. While deterring heat buildup, the thin, patterned silica material does not block sunlight, allowing the photons to enter the solar panel where they are converted to energy. It’s a win-win situation, allowing the free flow of sunlight and the removal of excess heat from the system.   Cont'd...

OMG Roofing Products  - PowerGrip Universal

OMG Roofing Products - PowerGrip Universal

Eliminate Solar Rack Ballast and Reduce Rooftop Material Handling. PowerGrip™ Universal (PGU) is a commercial roof mount system designed to secure solar racks and other equipment to any type of commercial roofing system. PGU provides a secure connection directly to the roof deck or structural members and is designed to reduce or eliminate ballast in solar racking systems, so there's less weight on the roof and less material handling. Made of heavy-duty cast aluminum, PGU units include a base ring which is secured through the roofing cover and into the structural roof deck, and a waterproof top plate.
