AI Technical Summary
The difficulty in preparing high-quality quasi-two-dimensional perovskite polycrystalline thin films leads to less than ideal performance of perovskite photodetectors, especially when the crystallization is poor and the phase distribution is uneven, which affects photon absorption and carrier transport.
A quasi-two-dimensional perovskite photodetector based on naphthylamine was prepared by solution method. The crystallinity and phase composition of the polycrystalline thin film were improved by adding an appropriate amount of MACl to the precursor solution and using antisolvent control. The device structure consists of ITO conductive glass, PEDOT:PSS anode buffer layer, quasi-two-dimensional perovskite polycrystalline thin film, C60/BCP cathode buffer layer and Ag cathode.
A highly crystalline quasi-two-dimensional perovskite polycrystalline thin film was achieved, which improved the current response capability and photoelectric conversion efficiency of the photodetector, exhibiting performance comparable to that of solar cells, with good current output and photoelectric conversion capability.
