Self-healing solar material found

The findings — from the University of York — increase the prospect that it can also be feasible to engineer high-performance self-healing substances which can minimize charges and enhance scalability, researchers say.

The substance, known as antimony selenide (Sb2Se3), is a photo voltaic absorber cloth that can be used for turning mild power into electricity.

Professor Keith McKenna from the Department of Physics said: “The technique with the aid of which this semi-conducting fabric self-heals is as a substitute like how a salamander is capable to re-grow limbs when one is severed. Antimony selenide repairs damaged bonds created when it is cleaved via forming new ones.

“This capacity is as uncommon in the substances world as it is in the animal kingdom and has necessary implications for purposes of these substances in optoelectronics and photochemistry.”

The paper discusses how broken bonds in many different semiconducting substances typically outcomes in bad performance. Researchers cite as an example, some other semiconductor known as CdTe that has to be chemically handled to restore the problem.

Professor McKenna added: “We found that antimony selenide and the intently associated material, antimony sulphide, are capable to simply heal damaged bonds at surfaces thru structural reconstructions, thereby casting off the difficult digital states.

“Covalently-bonded semiconductors like antimony selenide locate enormous functions in electronics, photochemistry, photovoltaics and optoelectronics for instance photo voltaic panels and element for lights and displays.
