Scientists Develop Thin Films from Barium Zirconium Sulfide (BaZrS3)

Scientists have created thin films developed from barium zirconium sulfide (BaZrS3) and confirmed that the materials have alluring electronic and optical characteristics foretold by theorists.

The films combine powerful light absorption with good charge transport—two qualities that make them ideal for functions such as photovoltaics and light-emitting diodes (LEDs).

In solar panels, for instance, experimental outcomes suggest that BaZrS3 movies could be much more efficient at changing sunlight into electricity than conventional silicon-based supplies with identical thicknesses, says lead researcher Hao Zeng, Ph.D., a physics professor in the University at Buffalo School of Arts and Sciences.

This might decrease solar power costs, mainly as a result of the new films carried out admirably even when they had imperfections.

The examine was revealed in November in the journal Nano Energy.

UB physics Ph.D. students Xiucheng Wei and Haolei Hui have been the first authors. The venture-funded by a U.S. Division of Energy SunShot award and National Science Foundation Sustainable Chemistry, Engineering and Materials award—included participation from researchers at UB; Taiyuan Normal University, Xi’an Jiaotong University and the Chinese Academy of Sciences.

BaZrS3 belongs to a class of materials referred to as chalcogenide perovskites, which are non-toxic, earth-plentiful compounds.

Lately, theorists have determined that various chalcogenide perovskites ought to exhibit helpful digital and optical characteristics, and these forecasts have captured the interest and creativeness of experimentalists like Zeng.
