Solar engineers from the Univ. of New South Wales have developed an innovative method to dramatically improve the quality of low-grade silicon, promising to significantly improve electrical efficiency and reduce the cost of solar panels.
The UNSW team has discovered a mechanism to control hydrogen atoms so they can better correct deficiencies in silicon – by far the most expensive component used in the making of solar cells.
“This process will allow lower-quality silicon to outperform solar cells made from better-quality materials,” says Scientia Professor Stuart Wenham from the School of Photovoltaics and Renewable Energy Engineering at UNSW.
