Summary:PbS QDs with size of 7-9 nm were deposited by an in-situ room temperature solution chemical reaction process using lead nitrate cationic resource in a form of solid precursor film and ammonium sulfide as an anionic reaction solution. The TiO... film with PbS QDs deposited by the in-situ method was used to fabricate QDs-sensitized solar cells. The power conversation efficiency of the as prepared solar cells improved by increasing cycle numbers. For 7 deposition cycles of PbS QDs, the PbS/TiO... device shows an open-circuit voltage (Voc) of 538 mV, a short-circuit current density (Jsc) of 0.145 mA, fill factor (FF) of 0.416 and a power conversion efficiency (...) of 0.163%.
