Massachusetts Institute of Technology (MIT) research team has invented a paper thin solar batteries, solar cells are printed in "ink" form to ordinary papers and immediately generate electricity. MIT pointed out that the technology is cheap and simple, can be printed by the printer and able to charge iPad, clothes drying within two years.
MIT experiments show that the durability of "solar ink" made paper thin battery is high and sufficient to supply electricity usage for an LCD clock. If repeatedly fold the paper 1000 time the battery still remains its performance and functions. In addition, the lightweight paper battery is good to carry, can stick on the briefcase, a hat or folded close in pocket when needed and then spread out under the sun to generate electricity.

Currently, the conversion efficiency of solar cells is less than 2% which only able to provide power to electronic alarm clock and other small supplies of electricity, but researchers estimated that the conversion efficiency will be increase to 8% in 2 years to supply the application to electronic devices such as mobile phones, iPad and other low-power electronic devices.
