  • Layered polycrystalline lead selenide photoelectric film and fabrication method thereof
    Patent number: 11781222
    Abstract: The present invention relates to a photoelectric film and a fabrication method thereof, and in particular, to a layered polycrystalline lead selenide (PbSe) film and a fabrication method thereof. The fabrication method mainly includes: (1) fabricating a dense PbSe layer on a substrate through chemical bath deposition (CBD); (2) fabricating a loose plumbonacrite (Pb10O(OH)6(CO3)6) layer on the dense PbSe layer through CBD; (3) placing a sample with the dense PbSe layer and the Pb10O(OH)6(CO3)6 layer in a selenium ion-containing solution to allow an ion exchange reaction to finally form the layered polycrystalline PbSe film. The fabrication method has the advantages of simple process, low cost, and high controllability.
