The magic of photosynthesis in plants, is expected to help mankind achieve the dream of clean energy. Recently, this reporter received information from the Shanghai Science and Technology Commission, East China Normal University researchers use of nano-materials in the laboratory success of "recycling" chloroplast to achieve extremely low cost of solar energy power generation.
Chloroplast for photosynthesis in plants places, sunlight can be converted into chemical energy. The task force is not in the plant in vitro "copy" of a chloroplast, but the development of a structure similar to the chloroplast and the new battery - Dye-sensitized solar cells, solar energy into trying to power. Nano-earmarked funds in Shanghai, with the support of more than three years after experiments and exploration, this bionic solar photoelectric conversion efficiency of more than 10 percent, nearly 11 percent of the world's highest level.
As a third generation of solar cells, dye-sensitized cells is the biggest attraction of cheap raw materials and simple production process. According to estimates, dye-sensitized cells equivalent to the cost of silicon cells plate 1 / 10. At the same time, even if the sun is not enough room, its photoelectric conversion rate will not be affected significantly.
