So far the thinnest solar cells have come out

Hats, windows, white paper, balloons, what if they all generate electricity? Scientists at the Massachusetts Institute of Technology have developed an ultra light, ultra thin flexible solar cell that can be attached to many objects. Even lying on a soap bubble does not make bubbles deformed. This material has great potential and is of great value to more weight sensitive applications, such as spacecraft or high-altitude sounding balloons. It is expected to create many new fields for solar cell applications.

Massachusetts Institute of Technology said that this solar cell consists of a substrate and a coating of two parts, the thickness of only 2 microns, equivalent to the diameter of a human hair 1/50, 1/1000 traditional solar cells, solar cell is likely to be by far the thinnest and lightest. Vladimir Bilavik, Professor of electrical engineering at Massachusetts Institute of Technology led the study said: "this kind of battery is very light, such as integrating it into your shirt or laptop computer, you can't even feel their existence."

Bealawy J said that the technology's lead is in one step to complete the manufacture of all components. Because no other process is required, the probability of exposing the electronic components to dust and other contaminants is reduced, and the quality and performance of the product are guaranteed. At the same time, the simplification of production links is also possible for mass production.

Bealawy J's team has tested the idea and produced prototypes in the laboratory. They used parylene (parylene), a flexible polymer common to do solar cell substrate and coating with another called DBP (dibutyl phthalate) light absorbing layer made of materials. The entire manufacturing process is carried out in a vacuum chamber at room temperature without any solvent. Compared with conventional solar cells, there is no need for high temperature and toxic chemicals. In the vacuum chamber, the substrate and the solar cell unit can be "grown" by vapor deposition.

The solar cell can be used either as a traditional glass or as a fabric, paper, or plastic. Although the new device conversion efficiency is not very high, but because of light weight, power to weight ratio to dominate the world. A typical silicon solar battery module, the glass is a large part of the total weight, per kilogram can produce 15 watts of power, but a new thin film solar cells per gram can produce 6 watts of power, 600 times higher than the former.
