Perovskite can take the heat—Myth-busting research into a new alternative solar cell material…

[font size=4]Myth-busting research into a new alternative solar cell material could lead to cheaper solar cells[/font]
Published online Jul 20, 2016
[font size=3]Solar cells that are cheaper and easier to manufacture could challenge the dominance of silicon, with new research showing an alternative material called perovskite is more efficient and adaptable than previously thought.
…
Leong’s study showed the perovskite cells still worked at higher temperatures, with performance peaking at around 330 Kelvin — or 57 degrees Celsius — and then declining slightly after that, meaning their performance will be high even on a relatively hot rooftop. It also showed that, contrary to arguments made by some critics, the material was highly efficient at collecting charge through electrodes.
Leong believes that perovskite will eventually challenge silicon commercially. “In terms of efficiency, perovskite is already close and it can be made much more cheaply,” she says.
However, perovskite cells still contain lead, which means more research needs to be done to ensure the lead does not leak. “Another big challenge is to make cells big enough for commercial use, as right now all the research is on small cells,” she says.
