Fluorescent Dye Boosts Solar Cell Efficiency by a Whopping 38 Percent

See on Scoop.itGreen Energy Technologies & Development

Squaraine dye helps to improve light absorption, recycle electron and enhance the light to energy conversion in solar cells, increasing efficiency by a whopping 38 percent.

Duane Tilden‘s insight:

>The Yale researchers relied on Förster resonance energy transfer (FRET), a well-known biochemical mechanism, to achieve this radical new energy conversion rate.

“In this type of solar cell—FRET-based heterojunction polymer solar cells—extra energy is able to migrate from one molecule to another over long distances. The dye, which is highly absorbent in the near-infrared region, both broadens the spectral absorption of solar cells and enhances electricity transmission,” Physorg explains.<
