Solar technology is continually advancing . While not yet a source of energy that can compete with the others, carry out research and development that getting closer to the goal : A renewable energy source and ecological viable definitely be able to replace the production of electricity .
The latest advances in solar energy are directed toward obtaining or manufacturing biological components to transform the sun's energy into electricity.
Recently a group of scientists from Brigham Young University succeeded in isolating a protein found in bees. It is ferritin , which showed positive results when experiments were performed with sunlight. Almost simultaneously, Israeli scientists discovered that the wasp advantage eastern sunlight for energy for heating and as fuel to move their wings.
Both developments are important for solar technology and represent a small step towards a profitable and efficient solar energy . However, there is still much to do in this regard . In the case of protein researchers are trying to use to store energy in a battery. While Israeli scientists attempt to reproduce the structure of the oriental hornet to mimic its operation. In both cases encouraging results have been achieved so far .
Another breakthrough in solar energy comes from the hand of nanotechnology. Current solar cells are made from silicon , a material that is abundant on earth , but the silicon purification costs are very high. Recent research have developed a purification system that is much cheaper and more efficient .
Nanotechnology appears as the great ally of solar technology to create inexpensive solar cells and with acceptable performance . Nickel nanoparticles are used which act as quantum dots within the solar cells.
