Kesterite is a naturally occurring mineral composed of copper, zinc, tin, and sulfur (CZTS). It has long been recognized for its potential in solar cell applications. It is abundant, non-toxic ...

The team chose tungsten oxide (WO3) as a buffer layer based ... the two structures demonstrated that the addition of the BSF layer could increase the erformance of the CZTS solar cell.

Photovoltaics (PVs), devices that can convert sunlight into electrical power, are becoming increasingly widespread and more people worldwide are now relying on them to generate electricity. Renewable ...

Engineers at Australia’s University of New South Wales (UNSW) have claimed to have achieved a new world record for photovoltaic efficiency using high-bandgap kesterite solar cells (CZTS).

UNSW researchers have achieved a world record energy conversion efficiency of 13.2% for high-bandgap kesterite (CZTS) solar cells with a laboratory scale cell that had been enhanced with hydrogen.
