Scientists create new “ink” or printable solar PV cells

Polaris solar PV net news: news on July 28, according to media reports, new technology uses steam rather than a liquid, the temperature was less than 120 degrees, the “relatively benign” environment so that people can be general, not treated as paper, cloth, plastic substrate, printed solar cells on it. MIT scientists have developed a new “ink”, it is deposited on the surface of paper or other soft fabric, printed photovoltaic cells.

Latest technology and most of the method of manufacturing a solar cell is very different now. New technology uses steam rather than a liquid, temperature less than 120 degrees Celsius, these “relatively benign” environment so that people can be general, not treated as paper, cloth, plastic substrate, printed solar cells on it.

New technologies offer a cheap way to mass-produce solar cells. This technique called chemical vapor deposition is more complicated than printing regular documents, to print out an array of photovoltaic cells on paper, you need 5 layer of material deposited on this piece of paper, and this process must be conducted in a vacuum.

Latest technology you can use ordinary, untreated paper, including printing paper, tissue paper, carbon paper, and even newspapers, and it works very well, even after the paper is folded into paper airplanes, solar cells are still able to work on it. Scientists are also PET plastics, and printing out a piece of a thin solar cells, and fold open the 1000 times, and its performance is not affected.

Latest the conversion efficiency of solar cells is about 1% on this paper, but scientists believe that as they continue to improve on this material, conversion efficiency can be greatly improved. Massachusetts Institute of technology’s research is very exciting, solar research, many scientists are focused on the development of solar cells, in fact, the small solar applications is very wide.
