Solar energy technology is constantly advancing to find more efficient and longer-lasting forms of solar energy. Since solar energy is the renewable energy most widely available, the sector is very popular for study. Another new solar energy technology has just emerged, however, it is in the beginning stages.
As was just published in Nature Chemistry, a new solar technology which is able to repair its own solar cells in order to avoid solar cell degradation has emerged. The lead researcher is Michael Strano, who is a professor at the Massachusetts Institute of Technology (MIT). The basis of the regenerating cell is nature, particularly plants. Strano stated: “Nature has figured out how to work with solar energy. It makes a dynamic cell that can constantly repair itself.”
Current solar cell models are greatly impacted by the sun and eventually degrade and require replacing. These solar cells are able to regenerate and at the same time maintain their beginning efficiency rate. Current solar cell models eventually lose efficiency as they degrade.
The MIT regenerating solar cell is made up of a photosensitive protein, carbon nanotubes and phospholipids. The researchers then inject surfactants into the cell. These surfactants enable the materials to take on a structured form which can generate electricity. This surfactant ingredient is the key to the regeneration process–it can be added to continually keep the solar cell is original condition.
As previously stated, the technology is in its infancy and is not expected to be on the market anytime soon. Currently, researchers are working to increase the efficiency of the solar cells in order to make it more promising for use in homes and businesses around the world.
