UNSW Claims Efficiency Record For Large Perovskite Solar Cell

Researchers at the University of New South Wales (UNSW), which heads the Australian Center for Advanced Photovoltaics, have claimed a new efficiency record for perovskite solar cells.

Perovskite cells have represented one of the hottest topics among solar researchers, as the cells are often considered thinner, more flexible and easier to manufacture than conventional solar cells. However, commercialization of perovskite cells has been hindered by lower efficiencies.

UNSW’s Anita Ho-Baillie says she and her team have reached 12.1% efficiency for a 16 cm2 perovskite solar cell – the highest efficiency rating for such a large cell of its kind. Although higher efficiency ratings have been previously reported for perovskite solar cells, those records were for much smaller cells; in fact, UNSW says in an announcement, “The new cell is at least 10 times bigger than the current certified high-efficiency perovskite solar cells on record.”

The 12.1% efficiency record for the large perovskite solar cell was verified by Newport Corp., and the international testing center has also confirmed efficiency gains for other UNSW-produced perovskite cells.

“This is a very hot area of research, with many teams competing to advance photovoltaic design,” says Ho-Baillie in the UNSW announcement. “Perovskites came out of nowhere in 2009, with an efficiency rating of 3. percent and have since grown in leaps and bounds. These results place UNSW among the best groups in the world producing state-of-the-art high-performance perovskite solar cells. And I think we can get to 24 percent within a year or so.”
