Read an interesting post on CNET about MIT researchers printing a solar cell on paper! like all new developments it is still in its emryonic stage, not yet viable for mass production. The article by Martin LaMonica covers the MIT lab and it’s work on the latest technology indepth.
MIT is focusing much of its effort on quantum dots, or tiny crystals that are only a few nanometers in size. A human hair is about 50,000 to 100,000 nanometers thick. Using different materials and sizes, researchers can fine-tune the colors of light that quantum dots can absorb, a way of isolating good candidates for quantum dot solar cells.
These kind of developments are a positive step in the right direction. Martin says that if .3% of the US is covered by solar panels with 10% efficiency it can prodcue 3times the energy needed for the US consumption! May be in future we will be using staple guns to attach solar cells!
Vladimir Bulovic Director of the Eni-MIT Solar Frontiers research center says for any new discovery to be viable or fully developed takes up to 10 years!
