Changing the type of silicon etching drops solar power costs by more than 10 percent

Researchers have found that using dry etched black silicon for passive emitter rear cell (PERC) solar cells increases the cost of individual cell production by 15.8 percent to 25.1 percent, but reduces the cost per unit power by 10.8 percent over those for industrial Czochralski silicon.
