We must admit that solar technology is still in its infancy level, but it can also be encouraged to grow up as an adult. To be honest, the future depends a lot on public and private investment. We are really happy that large companies are not waiting for any top technologies to get like 100% efficiency. They have already begun to invest billions of dollars, and we hope that their efforts will be a never ending process as sunlight. Even search engine giant Google has already invested $ 160 million, the largest solar power tower in the world. Europe, America and Asian countries like Japan and China have been investing billions of dollars per year.
There are 2 ways to make solar power available to a large extent. Either we need to increase the efficiency of traditional energy or do we have a new technology that is cheap, but produces the same amount of energy to be found. With traditional technology, we get only 11-16% efficiency, where it is theoretically possible to get to 30%. Got for most of sunlight scientists researched incessantly. But it is not always possible to bring a product form Laborfabrik, but they will continue to do their work without interruption.
Scientists have a cell named "Grtzel" cell produced. It does not need direct sunlight like typical solar cell. In addition, it is cheaper, has higher efficiency, and it will save wasted land.
"Radiant Solar entrepreneur" is a new technology in which the frequency of the light shifted to another wavelength is obtained and then the light can be emitted again.
Another area of research includes 3-D nano-cone-based solar cell, which can be increased approximately eighty percent of the efficiency of photovoltaic cell!
Another research area comprises carbon nanotubes. MIT engineers have theses with carbon nanotubes, which can store 100 times more power than conventional solar photovoltaic cells.
Another research project called "Photon Enhanced thermionic emission," or PETE. This technology uses sunlight twice in contrast to conventional technology. It is perfect for solar parks suitable for roofs.
Even the eyes of flies are used. It sounds like something special, but it's true. Probably we have to wait some more.
It is believed that solar energy is developing exponentially. It is doubling every two years. So, if it continues as in this way, only 20 years is needed to ensure us to supply 100 percent! According to the International Energy Agency (IEA), quarter of the world's energy needs would have to be postponed until 2050 are available and after European Photovoltaic Industry Association (EPIA) and Green Peace International by solar energy, investing in solar technology around the world would be double by 2015 . They also believe that 12% of total energy consumption in Europe was covered worldwide by 2020 and 9% of total energy consumption by 2030 through photovoltaics. There were some major problems with the pricing of PV modules, but is very inspiring figure that since 2005, prices fell by 40% and 40% more are expected to decline by the year 2015. Good luck solar energy!...
