“Poking holes” in solar cells the secret to Aussie perovskite world record – RenewEconomy

Australian researchers have revealed the secret to a record-breaking perovskite solar cell design in a new paper, saying that poking holes in poorly conducting materials was key to improving performance.
The research team, based at the Australian National University, achieved a conversion efficiency world record for next generation perovskite solar cells, the amount of solar energy converted into useful electricity, of 21.6 per cent.
The record was first reported August last year, but the details…
