In article number 1902933, Ju‐Won Jeon, Sung‐Yeon Jang and co‐workers report high‐efficiency colloidal quantum dot solar cells (CQDSCs) without using solid‐state ligand‐exchange (SSE). By employing molecular engineered π‐conjugated polymer‐based organic hole transport materials, the power conversion efficiency (PCE) of the CQDSC reaches 11.53%, which is the best among SSE‐free CQDSCs. This technique paves the way for improving the PCE of CQDSCs further.
