I didn't know the Guiness Book awards solar cell efficiencies lately. This story I read on Cleantechnica tells how SunPower, "the most popular solar panels company in California," got into the Guinness Book for providing people with "the most efficient commercially available photovoltaic modules on the market."

Global Solar, a solar cells manufacturer, has just developed and released a flexible solar panel designed for flat commercial rooftop buildings. The modules, consisting of solar panels 19 feet long and 1.5 feet wide, are actually made with CIGS (copper, indium, gallium, selenium) cells that work as well as their rigid counterparts.

High efficiency solar cells are for the moment only available to space applications, because of their prohibitive costs. The Eindhoven University of Technology from The Netherlands, with a EUR 1.2 million help from the Dutch government wants to develop ultra-efficient solar cells that are also cheap. They envision their cells having a 65% efficiency, something even the satellites would envy.

They used Fresnel lenses situated 10 cm apart from stacked layers of solar cells. The metamorphic triple-junction solar cells consist of gallium indium phosphide, gallium indium arsenide and germanium semiconductors. The efficiency of these cells is dazzling: 41.1 percent - higher than ever before. The two scientists even for the 2010 Joseph von Fraunhofer Prize.

Some solar energy adopters wish to use their solar panels in the classic manner - installed on a roof or in their backyard. Still, there are situations where installing a flat solar panel is near to impossible, due to space limitations in places like corporate buildings or where aesthetics matters.

Ryszard says it's much more efficient to assemble solar cell this way than put them directly into light, where you'll lose a lot through reflection back into the environment. Some recently invented anti-reflective coatings may even accelerate the light's absorption into the solar cells. This is one of the advantages.
