This cloudy-day black silicon solar cell can hit a record 22.1% efficiency

Researchers at Finland’s Aalto University have achieved a record-breaking 22.1% efficiency for a nanostructured silicon, or black, solar cell. They accomplished this by overlaying a thin, passivating film on the nanostructures by a process known as atomic layer deposition, and by integrating all of the metal contacts on the cell’s back side.
Perhaps the best part: Black solar cells work really well on cloudy days. “This is an advantage particularly in the north, where the sun shines from a low angle for a large part of the year,” said professor Hele Savin from Aalto University, who coordinated the study, in a statement. “We have demonstrated that in winter Helsinki, black cells generate considerably more electricity than traditional cells, even though both cells have identical efficiency values.”
Using the aforementioned process, the team managed to beat their previous record by almost 4%, which is a stunning achievement. The new cells have a certified external quantum efficiency of 96% at 300nm wavelengths, which the team said shows that charged carrier surface recombination is no longer a problem — and that for the first time, the black silicon isn’t limiting energy conversion efficiency. And thanks to the inherent properties of black solar cells, they can capture solar radiation at low angles, generating more electricity over the full duration of a day as compared with traditional cells.
