Remember the stories about Leonardo, who was flying the birds to understand how they could stay in the air and imitate the principles? Here, the Leonardo are now studying at MIT and the photovoltaic cells from plants .
E 'known that one of the problems of the photovoltaic solar cells deterioration. The conversion of sunlight into energy through chemical processes is in fact consuming part of the cells, destroying some materials.
A similar thing happens during photosynthesis in plants: the transformation of light energy (sugars in this case) involves the destruction of some proteins, but the plants have "learned" to regenerate.
What they did, researchers at MIT was just studying this process to create self-healing photovoltaic cells with molecules able to break down and reassemble
protein, vegetable fat, carbon nanotubes form the molecules that can convert light into energy. A surfactant molecules then act to disrupt the relief that, upon removal of the surfactant, to rebuild back to full efficiency.
Tests have already 'given good results, beating the ten hours of full efficiency after several cycles of reassembly, but we must still wait for some time epr see this technology on the market.
