Research Develop Microscopic Solar Cells Can Self Repair
I always like it when things fix themselves. From my internet to my car, I am always hoping that when things go wrong, they will simply correct themselves. Now, scientists have developed a tiny solar cell that can do just that.
Researchers have demonstrated tiny solar cells just billionths of a metre across that can repair themselves, extending their useful lifetime.
The cells make use of proteins from the machinery of plants, turning sunlight into electric charges that can do work.
The cells simply assemble themselves from a mixture of the proteins, minute tubes of carbon and other materials.
The self-repairing mechanism, reported in Nature Chemistry, could lead to much longer-lasting solar cells.
