摘要：
The hexagonal plate lead iodide (PbI2), with band gap energy of 2.31 eV, was firstly synthesized from mixed sulfide-oxide lead and zinc ore by an in-situ reduction-selective leaching-precipitation approach, and the recovery efficiency of lead reached 92.30%. When the formed PbI2 was used to fabricate a perovskite solar cell (PSC), the power conversion efficiency (PCE) reached 14.98%, equivalent to that of the PSC from specpure PbI2. This work developed a new process for high value-added utilization of the mixed ore.
