Researchers at the Massachusetts Institute of Technology (MIT) have developed the lightest and thinnest solar panel with high power ratings, just 2 micrometers thick. The battery is so light that if you put it on a soap bubble, it won't burst.
The cells of the solar panel were assembled in a vacuum chamber, which completely eliminated the ingress of dust and other particles that could have the slightest negative impact on the efficiency of the product. The light-absorbing layer itself consists of an organic DBP material that is sandwiched between the substrate and the parylene protective coating. Parylene is a polymer coating commonly used to protect printed circuit boards and biomedical implants.
The production of solar cells is usually associated with high temperatures and the use of harsh chemicals. Solar panels developed at MIT can be created at room temperature using a technology known as vapor deposition. Scientists believe that soon it will be possible to organize their mass production.
Max Stein, professor of materials science and engineering at the University of Michigan, believes that such a unique ratio of battery power to weight opens up prospects for their use in space and electronics.
