Cascade surface modification of colloidal quantum dot inks enables efficient bulk homojunction photovoltaics
It is challenging to realize doping and surface passivation simultaneously in colloidal quantum dot inks. Here Choi et al. employ a cascade surface modification approach to solve the problem and obtain record high efficiency of 13.3% for bulk homojunction solar cells based on these inks.
