Lead sulfide colloidal quantum dot (CQD) solar cells with a solar power conversion efficiency of 5.6% are reported. The result is achieved through careful optimization of the titanium dioxide electrode that serves as the electron acceptor. Metal‐ion‐doped sol‐gel‐derived titanium dioxide electrodes produce a tunable‐bandedge, well‐passivated materials platform for CQD solar cell optimization.
