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.
