Existing Solar Energy Conversion Technologies ensure the disposal of only a small part of the solar spectrum radiation, and even with an efficiency of not more than 15% for the most advanced (and very expensive) development. Most of the spectrum attributable to low-energy – red and infrared – radiation, disappears in vain.
IBM-created high concentration system photovoltaic and heat energy (HCPVT) allows utilize solar energy over a wide range of spectrum radiation of the Sun, increasing the efficiency of its use in 2000 time. According to the developers, in the future they are capable of raise the ceiling for safe production efficiency electric and thermal energy 5,000 times!
In the process of capturing sunlight additionally desalination of cooling water, which can also go for air conditioning so a relatively small installation can provide energy to the whole village.
In the HCPVT system, heat is absorbed by hundreds of tiny solar batteries – photovoltaic chips. Chips collect energy and then cooled by water circulating through microchannels, so they able to concentrate so much solar energy.
Each 1X1 cm chip can convert to solar the region is about 200-250 watts per regular eight-hour work day. IN HCPVT system, the cooling water is heated to 90 degrees Celsius, then water passes through a porous membrane a distillation system where it is then vaporized and desalinated. Such a system can provide 30-40 liters of drinking water per square meter receiver per day, at the same time production electricity with an efficiency of more than 25 percent will be about two kilowatt hours per day.
According to Greenpeace, this technology can establish itself in as the third largest source of sustainable industrial electricity production. In a study published in 2009 year, proven that solar energy can cover the whole world need for energy. According to Greenpeace, enough for this only two percent of the Sahara desert.
This project is funded by the Swiss Technology Commission and innovation. She provided a three-year grant of 2.4 million dollars to develop technology. Prototypes are already developed and are being tested.
