MIT develop smallest solar-cell

It also does not require any further maintenance such as washing or being taken off from the vacuum during fabrication.

The solar cell is believed to be the next proficient power source for many small devices. But as devices get smaller and efficient, the need to have a source of energy with this same properties is a priority. MIT have created such a cell that would work for most small low-power devices. They have created the thinnest and lightest solar cell to date.

The head researcher in this project, Vladimir Bulovic, from MIT, said that they created this power source by combining all the critical steps to one. They formed the substrate of the cell and the protective overcoat in one process. He also said that the substrate is built in place and sides not need to move around. It also does not require any further maintenance such as washing or being taken off from the vacuum during fabrication.

"You can come up with the substrate as you grow the device, "said Vladimir Bulovic." We are still in experimental stages, but we have noted considerable progress in making this solar cell a reality. We hope our research will lead to better power sources."MIT are also using organic material in place of perylene, and a polymer called DBP to create both the overcoat and substrate.

Usually, perylene is used as an overcoat for biomedical devices to offer protecting to the apparatus. Using DBP for the cell has enabled the company to create the power source at room temperatures in a vacuum. It also does not need the use of harsh chemicals or elevated temperatures to merge the elements together. This makes the whole process economically viable and safer.
