Latest Patents

Junlin Liu holds a patent for a "Layered polycrystalline lead selenide photoelectric film and fabrication method thereof." This invention relates to a photoelectric film and its fabrication method, specifically targeting the creation of a layered polycrystalline lead selenide (PbSe) film. The method involves several key steps: first, a dense PbSe layer is fabricated on a substrate using chemical bath deposition (CBD). Next, a loose plumbonacrite (PbO(OH)(CO)) layer is added on top of the dense PbSe layer through CBD. Finally, the sample undergoes an ion exchange reaction in a selenium ion-containing solution, resulting in the formation of the layered polycrystalline PbSe film. This method is notable for its simplicity, low cost, and high controllability. The resulting PbSe film consists of a lower dense polycrystalline cubic PbSe layer and an upper loose polycrystalline cubic PbSe layer, making it suitable for various applications in photoelectric conversion and thermoelectric conversion, including infrared sensors, solar cells, laser emitters, and thermoelectric converters.
