Bumpy solar cells could harvest up to 66% more energy

Solar cell efficiency may get a bump from bumps. New research suggests that building tiny domes into the surface of organic solar cells could boost their efficiency by up to two-thirds, while capturing light from a wider angle.

New research suggests that building tiny domes into the surface of organic solar cells could boost their efficiency by up to two-thirds, while capturing light from a wider angle. Scientists have toyed with other shapes for the surface, including embedding spherical nanoshells of silica which trap and circulate sunlight to allow the device to capture more energy from it. For the new study, scientists at Abdullah Gül University in Türkiye ran complex simulations of how dome-shaped bumps might boost organic solar surfaces.
