Efficiency record for black silicon solar cells jumps to 22.1%

Efficiency record for black silicon solar cells jumps to 22.1%

“The researchers have obtained the record-breaking efficiency of 22.1% on nanostructured silicon solar cells as certified by Fraunhofer ISE CalLab. An almost 4% absolute increase to their previous record is achieved by applying a thin passivating film on the nanostructures by Atomic Layer Deposition, and by integrating all metal contacts on the back side of the cell.”

Nanowires give ‘solar fuel cell’ efficiency a tenfold boost | (e) Science News.

To connect an existing silicon solar cell to a battery that splits the water may well be an efficient solution now but it is a very expensive one. Many researchers are therefore targeting their search at a semiconductor material that is able to both convert sunlight into an electrical charge and split the water, all in one; a kind of ‘solar fuel cell’.”

“State and federal financial incentives have also helped, they say, but it’s the passage of a state law in 2013 allowing group net metering that has really made solar power more cost-effective and accessible.
The law allows renewable energy facilities to share surplus electricity they produce with other people, and get paid for it. The catch is the people using the electricity have to be customers of the same utility company as the facility’s owner.”
