Latest Patents

Guiwu Liu holds a patent for a "Layered Polycrystalline Lead Selenide Photoelectric Film and Fabrication Method Thereof." This invention pertains to a novel photoelectric film and its fabrication method. The process involves several key steps: first, a dense PbSe layer is created on a substrate using chemical bath deposition (CBD). Next, a loose plumbonacrite layer is formed on top of the dense PbSe layer, also through CBD. Finally, the sample undergoes an ion exchange reaction in a selenium ion-containing solution, resulting in the layered polycrystalline PbSe film. This method is advantageous due to 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 and thermoelectric conversion, including infrared sensors, solar cells, laser emitters, and thermoelectric converters.
