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.<
