New technology to increase lifespan of solar cells

London, Feb 26 : Scientists have found a way to increase the lifespan of solar cells by coating them with a material that converts ultraviolet photons into ones of visible light.

According to a report in New Scientist, this new technology, known as "photon conversion material" (PCM), converts harmful UV into longer wavelengths, enhancing efficiency of solar-energy conversion and reducing damage to cells.

This should help the solar cells last longer, as well as increase their electrical yield.

The researchers have demonstrated through some experiments that the PCM could be made of a liquid, a gel, nanoparticles or a solid.

In experiments, the research team added the polymer blue polyfluorene to solar cells and found that it did indeed reduce the damage caused by UV light.
