Problems solved by technology
The invention discloses a polyvinylpyrrolidone cathode interface layer prepared by an adsorption method and its application. The method includes: immersing a substrate covered with a transparent conductive electrode in a polyvinylpyrrolidone solution, then taking it out and blowing it dry. In the invention, the substrate covered with the transparent cathode is immersed in the PVP solution, and the interaction force between the PVP molecules and the cathode molecules is utilized to obtain a uniform and continuous thin-layer PVP cathode interface layer without introducing traps in the active layer. The OSC of the PVP cathode interface layer prepared by this method has a photovoltaic efficiency comparable to the OSC of the PVP cathode interface layer prepared by the traditional method. The invention provides a method for preparing a PVP cathode interface layer by adopting an adsorption method, which is not limited by the PVP thickness resistance or printing technology, and is suitable for a large-area printing process.
