I came to this article about the Sunflower’s Fresnel lens . Those lens concentrates sunlight more than 1,000 times, enabling cheaper electricity than traditional photovoltaics. The system is self-powered. Technical specifications: 200-watt system features trackers that shift with the sun’s location, as well as a controller and communications system. The low-slung Sunflower is built to

Several months back Sharp, the biggest maker of solar panels in the world, has invested 72 billion Yen (~$725 million) into a plant that will make thin film solar cells in Sakai, in the Osaka prefecture. The production will start in March of 2010, with an initial annual capacity of 480 megawatts, bringing Sharp’s total

The average efficiency of regular solar panels is 15 percent; thin-film solar cells register a lower efficiency percentage than that. Japan’s National Institute of Advanced Industrial Science and Technology (AIST), however, claims 17.7 percent efficiency for its flexible thin-film CIGS solar cell. To be able to achieve that impressive percentage, AIST devised CIGS technology called

Solar panels developped by construction company that use peel-and-stick technology to attach to roofs. The company is called Lumeta, a subsidiary of DRI. Just watch the video. The roof is done in minuts…. Incredible…… “Solar needs to become part of the building envelope and this is a step towards that,” said Stephen Torres, COO of

IBM becomed a partner with company Tokyo Ohka Kogyo (TOK). IBM wants to develop cheaper and more efficient solar power technologies based on CIGS ( copper-indium-gallium-selenide ). Those cells should be more than 15% efficient. This is much more efficient than usual 6% to 12% efficiency that current (CIGS) solar cells have achieved. Classic photovoltaic
Thin-film solar cells more competitive and more efficient !!

CIGS cells use extremely thin layers of semiconductor material applied to a low-cost backing such as glass, flexible metallic foils, high-temperature polymers or stainless steel sheets. Thin-film cells require less energy to make and can be fabricated by a variety of processes. Because of this, they provide a promising path for providing more affordable solar

Thist time it’s for good. I beleive that this technology will bring the solar energy to the masses. Let’s have a look. I already talked about Nanosolar’s flexible solar panels which can lower the producing costs. But few days ago Konaraka announced succesfull testing a inkjet printing technology to produce a solar panels. “Inkjet printing
Solar Panel 80% Efficient of absorbing radiation ? Works at Night?

Steven Novack from the Idaho National Laboratories found a cheap solar panel, which is foldable and is about 80% efficient when it’s to absorbe the radiation from the sun. This is as twice as much as an conventional solar panel, made from silicone. Silicone solalr panels ar at their best, only efficient only for about
