For some solar cells, the future may be fluorescent.

Scientists at Yale have improved the ability of a promising type of solar cell to absorb light and convert it into electrical power by adding a fluorescent organic dye to the cell layer. This squaraine dye boosts light absorption and recycles electrons, improving the conversion of light into energy. The results suggest a new route for the development of lower-cost, higher-efficiency photovoltaics, the scientists said.

“People can apply our approach in designing advanced solar cells with higher efficiencies,” said André D. Taylor, the assistant professor of chemical and environmental engineering at Yale who led the research, published May 5 online in the journal Nature Photonics. (more…)

Innovations by a team of Yale University researchers could lead to improvements in basic solar power technology that result in lower-cost, higher-efficiency photovoltaic systems.

Photovoltaics (PV) directly convert sunlight into electricity. PV systems can be arrayed on rooftops to generate electricity for entire buildings, among other uses. Less expensive, more efficient systems could encourage broader use of this clean energy technology. (more…)
