Heterovalent cation substitutional doping for quantum dot homojunction solar cells

To use colloidal quantum dots in applications such as p-n junction solar cells, doping of the quantum dots is needed. Here, Stavrinadis et al. achieve lead sulphide quantum dot p-n homojunctions by heterovalent cation substitution of lead using bismuth.

The role of surface passivation for efficient and photostable PbS quantum dot solar cells

Controlling the surface of quantum dots has enabled higher efficiency in quantum dot solar cells. Now, the role of surface passivation and suppression of hydroxyl ligands in the performance and photostability of cells with an efficiency of 9.6% is unveiled.
