A coupled PbS quantum dot film and a PSBTBT:PCBM bulk heterojunction layer contribute comparable photocurrent in a new stacked solar‐cell architecture with sensitivity in the near infrared and an efficiency >4%. With a focus on the energy level alignment between components, time‐resolved microwave photoconductivity is used to elucidate the charge transport pathways for electrons and holes.
