Promising new material has the right properties to capture solar energy, split water into hydrogen and oxygen

Over the last several years, perovskites have garnered interest as materials to boost the efficiency of silicon-based solar cells through tandem designs that integrate a perovskite cell directly onto a high-efficiency silicon cell, but they contain a small amount of lead. If they were used for energy harvesting in a solar farm, the lead could pose a potential environmental hazard.

In 2016, using computer simulations to identify alternative materials, the researchers found a new type of lead-free perovskite with potential for high-efficiency solar cells.

The present paper shows these new materials may also split water.

“These new double perovskites are not only promising as a complementary material for tandem solar cells, but they can also be promising in areas like photocatalysis,” Volonakis said.
