Problems solved by technology

However, there is still a certain gap between the service life of all-polymer solar cells and inorganic photovoltaic cells, and it is necessary to further improve the thermal stability of all-polymer solar devices in order to realize the application
Although the photothermal stability of all-polymer cells has been greatly improved compared with fullerene and small molecule acceptor cells, the efficiency of the reported devices still decays in a short period of time

Abstract

The invention discloses a crosslinkable naphthal-diimide-based all-polymer solar cell receptor material and a preparation method and application thereof. A ternary random polymer with different olefinic bond contents is prepared by adjusting the composition of monomers containing olefinic bonds and is subjected to high-temperature thermal treatment; also disclosed is how to acquire a crosslinked-structure active layer material at the premise of maintaining high photoelectric conversion efficiency in order to except to obtain an all-polymer solar device having high photoelectric conversion efficiency and excellent thermal stability; application in the field of organic solar cells is achieved. In addition, the preparation method is simple; the material acquired has better resistance to hightemperature and better thermal stability when applied to photovoltaic material active layers as compared to common polymer donor/receptor photovoltaic material active layers; therefore, the material herein can be applied to the field of all-polymer solar cells to provide significantly improved stability for devices.
