Abstract: Disclosed herein are homogeneous CQD bulk homojunction solids prepared through a cascade surface modification (CSM) strategy. The CSM includes an initial halogenation step of CQD surfaces to attain an initial sufficient passivation; and a subsequent step that reprograms CQD surfaces with functional ligands to control the doping character and solubility properties of the resulting CQD inks. The resulting p-type and n-type CQDs exhibit a distinct potential difference, which induces a built-in electric field between the constituent classes of CQDs. By controlling the colloidal solubility of the inks, homogeneous CQD bulk homojunction films have been achieved, whereas it is shown that the use of prior ink strategies results in inhomogeneous films as a result of poor miscibility. The homogeneous CQD bulk homojunction films exhibit a 1.5-fold increase in the carrier diffusion length and outperforms previously-reported CQD solar cells, achieving a record PCE of 13.3%.
