Nanostructures Trap Photons in Ultrathin Solar Cells
In the quest to make sun power more competitive, researchers are designing ultrathin solar cells that cut material costs. At the same time, they’re keeping these thin cells efficient by sculpting their surfaces with photovoltaic nanostructures that behave like a molecular hall of mirrors.
“We want to make sure light spends more quality time inside a solar cell,” says Mark Brongersma, a professor of materials science and engineering at Stanford and co-author of a review article in Nature Materials.
