Highly efficient optoelectronic devices based on colloidal heterostructured quantum dots

Recently, significant progress has been made in colloidal quantum dot (QD) based optoelectronic devices for solar energy conversion, such as solar cells, luminescent solar concentrators, and solar-driven photoelectrochemical devices. In this Research Update, we summarized the most recent works on the QD based optoelectronic devices. Particularly, we focused on the effect of the QD structure on the functional properties of QD based devices. The major factors that determine the efficiency of the optoelectronic devices were discussed. In the end, we proposed potential ways to address the future challenges and opportunities of this field.
