Weekend Read: Pushing perovskite PV limits
The perovskite solar race is heating up, with a cue of manufacturers forming to test products at the US Department of Energy’s (DoE) PV commercialization facilities, and academics on both sides of The Pond announcing new advances in recent months.
Inverted blade-coated perovskite cell with 23.2% efficiency
A US research team has improved the efficiency of a blade-coated perovskite cell with a p-i-n structure by reducing iodine-induced charge traps in the films. They used the cells to fabricate a mini module with an efficiency of 18.2%.
‘Spontaneous de-doping’ for 17.8%-efficient perovskite mini-module
U.S. scientists have found a new ‘de-doping’ process in perovskite solar cells that could cut production costs and produce better devices. They have used this to fabricate a mini-module with 17.8% efficiency.
