TiO2

The record feat compares to usual figures of 2-3% for such devices. The Taiwanese scientists who developed the cell said it was prepared with the Silar method and is based on a ternary metal sulfide-alloyed semiconductor. They claim performance could be further boosted.

The Australian research team which developed the device said the higher efficiency was achieved through a nanowire design which eliminates the interface inside the titanium dioxide band.

Researchers from three Japanese universities have developed a process based on inkjet printing they say could reduce the cost of perovskite solar cell production. The group fabricated small cells with efficiencies as high as 13.19%, a figure they claim is promising enough to offer the possibility of scaling up to commercial production.
