Within a few years, the rigid silicon wafers manufactured today can be replaced by other materials and new technologies, moreover, may apply in a variety of functions .
Silicon is the material used for manufacturing photovoltaic panels, but the price is expensive. What has led to research and development of a second generation that creates films much more flexible and thinner than their predecessors. Thus, several companies worldwide, are working in what experts call low-cost solar panels and using materials other than silicon microstructures called CIGS because use copper, indium, gallium and selenium, or CIS in the case of not including gallium. Other researchers have created technologies such as organic photovoltaic cells (OPV), organic plastics one capable of reacting to light.
The potential of these materials are huge but its efficiency is still lower than silicon but proponents say it's just a matter of time to overcome. Some experts estimate it could be cost-effective to overtake fossil fuels from 2015.
addition, researchers and companies around the world are working on the development of various technologies such as so-called quantum hollow, nanotubes carbon or titanium oxide nanostructures dye. With them is expected to create a painting that recubrirĂa houses or roads to generate power, as well as dyes for all types of electronic equipment, textiles or solar cars.
Another generation of solar panels join nanoparticles with polymers to achieve more efficient and cheaper cells. The panel would be based on polymer nanoparticles that not only draw on the different types of light but also the infrared spectrum. NASA has used this multi-junction technology in their missions to Mars.
Some experts speak of advances in manufacturing cost-efficiency energy conversion because the cost would drop as well to compete with fossil fuels and nuclear energy.
The availability of renewable and clean energy are a reality toward which we move, so unstoppable, and this is a sure path to hope, but we must put all our energies on supporting governments that be willing to bet, definitely, on the development and implementation. can no longer continue to deny the facts. must be saved from this fire as much as possible and not make the mistake of continuing to seek new sources of fossil fuels and which apparently can be in the Arctic.
