In this work, with the introduction of nanostructures in the PbS-based hybrid system, we show an enhancement of photovoltaic performance in both visible and near-IR regions. The addition of increases the power conversion efficiency from 0.006% to 0.12%. With the aid of energy band-diagram, we show that excitons generated in PbS even in the near-IR range can now become dissociated to yield photocurrent in the external circuit.</p>1 aGuchhait, Asim1 aRath, Arup, Kumar1 aPal, Amlan, J.  uhttps://library.ncl.res.in/content/near-ir-activity-hybrid-solar-cells-enhancement-efficiency-dissociating-excitons-generated
