"Australian scientists have joined an elite club of just eight around the
world, making a perovskite solar cell that can hit 30 per cent efficiency.
Led by storied University of Sydney professor Anita Ho-Baillie, the Sydney
team’s work was weighed and measured by the US National Renewable Energy
Laboratory (NREL).
“It shows that we are capable of producing high performance cells. The next
step we will achieve is higher performance, either by double junction or triple
junction,” Ho-Baillie says.
“Triple junction has a theoretical efficiency of around 50 per cent. And we’re
also working on making sure the perovskite lasts as long as silicon cells.”
The Sydney researchers built a monolithic perovskite-Si tandem solar cell which
swapped out lithium-iron for morpholinium bromide (MLBr) as the perovskite
material.
They coated the silicon panel with perovskite, to make a double junction cell –
that is, when another light absorbent material is stacked on top of the
silicon.
“We directly fabricate that onto the silicon,” Ho-Baillie says.
“Double junction has a theoretical limit of around 40 per cent so we’ve still
got a good way to go but the NREL result is a very good milestone.”
Only eight other groups around the world have beaten the 30 per cent threshold
in the NREL lab."
