A thin film of quantum dots (QD) was used to visualize the local photo‐response of polycrystalline CdTe solar cells by down‐converting an electron beam of high energy to photons of visible light. The efficient photon generation in the QD film is compared to cathodoluminescence of the high‐purity bulk semiconductors and phosphor.
