New breakthrough in solar cell research at China Northeast Normal University

Recently, the team of Chin Northeast Normal University Yichun Liu and Xintong Zhang cooperated with the University of Tokyo in Japan to construct n/p quantum junction solar cells through PbS quantum dot surface ligand engineering, and achieved a photoelectric conversion efficiency of 10.5%. This is the highest efficiency reported for quantum junction PbS solar cells so far.

This breakthrough indicates that quantum dot solar cells can achieve wide-band photoelectric conversion covering the ultraviolet-visible-near-infrared spectrum, and can use simpler processes to prepare high-efficiency and high-stability quantum dot solar cells.
