2 watt  monocrystalline solar cells – Click on picture for placing an order.

Superior Class A Monocrystalline Solar Cells. These cells have no facial marring and a uniform deep blue phosphorous layer. These cells are used to create high-quality, DIY solar panels and can be assembled in series to make solar modules that exceed production quality, while saving hundreds of dollars off retail.There are now alot of online sellers selling Evergreen,Motech and German castoff cells that do not rate as the advertised wattage or are thin line errs.We have never done this and never will.We do not prey upon the lack of knowledge of new,inexperienced buyers and want solar accepted and used as widely as possible.Its is not only good for business but the future of solar energy! This sale is for 36 solar cells.

Traditional solar cell, “Thin-film does not mean its off”

Higher efficiency yields benefits in limited areas
Given the persistently high price of crystalline silicon solar cell manufacturers increasingly set the thin-film technologies that do not require the expensive raw material. So will the German photovoltaic specialist aboard Q-Cells in the CIGS technology and has formed a joint venture with the Swedish Solibro. According to experts, means the increasing involvement of producers in terms of thin film but not the end for the traditional solar cell. “We tend to see the film cells as a supplement,” said Sal Oppenheim analyst about Stephan Wulf.
Especially in the effectiveness, the silicon cells currently in the lead. “Especially in applications that require higher efficiency and greater output – such as the use of limited space – have the advantages of silicon cells,” says Wulf. By 2010, analysts project a global market share of thin-film technologies of around 20 percent. Until then, should the silicon prices have relaxed high, which presses currently on the mood of the solar industry.
Q-Cells, claims to the second largest manufacturer of solar cells, its existing technology portfolio will in any event extend to the thin-film CIGS technology. In the planned joint venture with Solibro, the company has secured a share of 67.5 percent and pays for the time being four million €. The payment of a further 20 million euro makes Q-Cells on the achievement of technological milestones dependent. Plans to build a factory in Thalheim with an annual capacity of 25 to 30 MW. For the first stage of Q-Cells will spend about 60 million €.
Already reached Solibro – a spin-off of the renowned Angstrom Solar Center, Uppsala University – at its pilot line modules with efficiencies of 11.5 percent. Under laboratory conditions had already been achieved efficiencies of up to 16.6 percent and 18.5 percent in mini-modules for cells, says Q-Cells. By comparison, the U.S. solar manufacturer SunPower has achieved in his latest classical solar cells after reported a conversion efficiency of at least 22 percent
