A nano-engineered hybrid material consisting of SWCNTs, PbS-QDs and a halide perovskite is developed for the first time. The PbS-QDs in the hybrid system are found to be a charge generator and a charge-transfer facilitator. The hybrid material integrated into photoconductive devices shows a broad spectral response.
