Dye sensitized solar cells are next-generation solar cells based on innovative technology. Unlike conventional silicon-based solar cells, dye-sensitized solar cells consist primarily of photosensitive dye and other substances. A dye-sensitized solar cell is a low-cost solar cell. This cell is also known as the Gratzel cell & was invented by Michael Gratzel and Brian O’Regan. It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system. It belongs to the group of thin film solar cells.
Solar Products in India are set to grow at a tremendous rate in the future driven by the declining costs of solar power and the increasing price of fossil fuel energy products.Already we are seeing massive power cuts across the country due to shortage of coal.Beside this,the prices of electricity has increased tremendously as well and is approaching seriously high levels due the increasing price of coal and gas.This has made it inevitable that people will turn towards solar products which are not only becoming cheaper but are also greener.Solar Products comes in a wide variety and range from almost all electrical home appliances.You can solar air conditioners,solar fans,solar toys etc.The main uses of solar products however are those in generating electric power .These are known as solar panels and poised to become ubiquitous in the days to come.The day is not far off when almost every house in India will have solar panels on their roofs to generate cheap electric power.Beside this solar lanterns are already replacing expensive and polluting kerosene lamps in poor households.Solar Lighting is also increasing particularly in those areas where the electricity power grid cannot reach.Solar Heaters have become extremely popular in southern India as solar water heaters are much cheaper than normal electricity powered water heaters.Though Solar Cookers have not caught on in a big way,there are also very cost effective and clean.Below is listed out the main solar products sold in India along-with their suppliers
Photovoltaic Cells have grown tremendously in the last few years spurred on by lowering costs and high demand in European countries like Germany.Photovoltaic Cell Manufacturers have also increased particuarly in low labor cost regions of Asia like China and Taiwan.In fact most of the solar panels have solar cells from companies in Asia.Solar Cell Manufacturers have incresased their capacity at a fast pace to meet the increasing demand.Currently due to oversupply of Photovoltaic Cells,the prices of solar cells have crashed with top quality solar cell prices almost 50% down from that one year ago.This is one of the best times to install solar cell panels in your roof given the rapid decline in the cost.Most of the independent solar cell suppliers are from Taiwan and some from China.European solar cell producers have mostly disappeared due to the high cost base of the European factories.
What are High Efficiency Cells High Efficiency Solar Cells are those Solar Cells whose average efficiency of converting solar energy into electricity is in general much higher than average by about 20-30%.Note common silicon solar cells have an average efficiency of between 17-19% which means that if 1000 kwh of energy is shone on this […]
Solar Cells are the basic building blocks of solar panels which are used to generate electricity from the sun.Note Solar Cells are made from Solar Wafers which are composed of Polysilicon the same material which is used to make your Electronic Products like iPods.While most people will never encounter Solar Cells since they buy and see Solar Panels,some enthusiasts want to make their own DIY Solar Panels.While in my opinion DIY Solar Panels are a Scam for people who are trying to save money ,its nonetheless a good thing for students and adopters.Its gives you an idea about how solar energy is converted into electricity.Note making solar cells is almost impossible for the layman so building your own solar panels requires you to buy solar cells.Nowadays solar panel prices have crashed making it easier to buy cheap solar cells on the market.
Solar Thin Film Companies are coming under siege again due to the relentless fall in the prices of crystalline silicon panels in recent months of 2011.Note large number of thin film companies went bankrupt the last time polysilicon prices fell off a cliff in the post Lehman crisis period in 2008 end.Applied Material the biggest solar equipment company killed off its SunFab Division which has a large customer list.Applied Materials saw the writing on the wall and concentrated its efforts on crystalline silicon equipment buying HCT Shaping and Baccini to become a billion dollar supplier of solar equipment.A number of weaker hands in solar thin film went out of business.However the prodigious growth in solar demand in 2010 saw large investments being made again.The biggest failure (not complete yet) seems to be the DOE and Obama darling CIGs startup Solyndra which has already used up a billion dollars with nothing much to write home about .Now Republicans are investigating whether the more than $500 million US government loan was done improperly.Abound Solar a CdTe startup has also managed a $400 million loan and I doubt whether it will manage to ever pay off the loan given that the lowest cost manufacturer of solar panels First Solar itself is under pressure from sharp cost reduction by integrated solar panel companies like Trina Solar.
