Amorphous Silicon Solar Panels were the big rage in 2-3 years ago when the prices of polysilicon the main raw material were touching $500/kg making the mainstream crystalline silicon solar panels very expensive.Amorphous Silicon (a-Si) on the other hand is a non-crystalline silicon which is deposited as an extremely thin layer on glass and other substrates.The cost of the silicon is much lower though the efficiency of solar cells which are made from a-Si is about half of those made from crystalline silicon.Applied Materials with its SunFab turnkey amorphous silicon (a-Si) equipment capitalized on this opportunity, lining up a number of customers with some customer orders in the range of a Billion Dollars.Oerlikon Solar was the other major thin film equipment market winning customers in Europe and China.Sky high poly prices also gave birth to numerous Thin Film startups planning to Manufacture and Use their own equipment rather than selling it .
Solar Thermal Technology has been facing tough competition from its sister Solar PV Technology in recent times.Despite strong government subsidies and support,numerous drawbacks have contributed to this Technology losing out to Solar PV in a number of projects in the US notably by Tessera.However a number of startups and big conglomerates continue to make huge investments in this technology.Spain and US are leaders in implementation of this Solar Technology type,however others like India and China are to building CSP plants as their energy needs continue to grow.Note like Solar PV,there are a number of different technology types for CSP like Power Tower,Parabolic Troughs,linear fresnel technology and Stirling Engines.Here is a list of the most important Solar Thermal Companies (Technology Providers cum Project Developers)
Solar Thin Film Technology has been growing rapidly despite falling costs of the mainstream Photovoltaic Crystalline Silicon Technology.While a number of Weaker Hands in Thin Film have downed shutters,Thin Film Producers continue to grow and expand.The massive growth potential of Solar Energy makes it possible for both of these PV technologies to flourish.Thin Film Technology unlike c-Si has a number of variants.Amorphous Silicon (a-Si),Copper Indium Gallium Sulphide (CIGs) and Cadmium Tellurium (Cd-Te) are the 3 main types of Thin Film Technology.There are a number of manufacturers of all of these 3 types of Technology.CIGs Technology is said to have the most potential in improving efficiency and competing with c-Si,however Cd-Te is currently the top dog as the world’s biggest solar producer First Solar currently uses this technology.a-Si Technology is not that hot with low efficiencies however Oerlikon and Sharp are pushing ahead with developing this technology.Here is a list of the world’s top Thin Film Companies.
Green Investing gone Haywire Masdar,Abu Dhabi’s Renewable Energy company is facing a rocky time as top executives have left the company or been shown the door.The resignation of its Research Head follows a long line of resignations and dismissals as its whole ambitious Renewable Energy strategy unravels.Masdar had tried to invest in almost every area [...]
Thin Film Technology came into prominence with Polysilicon Prices ruling at $400/kg Solar Thin Film Technology is supposed to be the 2nd Generation successor to the mainstream Crystalline Silicon (c-Si) Technology which accounts for around 85% of world production.With Polysilicon(c-Si raw material) being priced at an exorbitant $400/kg in 2008 (cost of $30/kg) due to [...]
Masdar’s Amorphous Silicon Division in Trouble Masdar, Abu Dhabi owned Green Company plans to build a Solar Thermal plant called “Shams 1″ near Abu Dhabi. Masdar PV has been in the news recently with the Dismissal of its top executives as its German Thin Film plant is facing trouble.Masdar PV sourced technology and equipment from [...]
