Abstract:

Since the emergence of organic-inorganic hybrid perovskite solar cells in 2009, after just over ten years of development, the photoelectric conversion efficiency has increased to more than 24%, which has attracted widespread attention. Due to their advantages of high electron mobility, adjustable energy levels and low temperature process for film-forming, fullerene materials can serve as electron transport layers (ETLs), additives in the perovskite layer, interfacial modification layers, and can even be employed in hole transport layer (HTLs) of PSCs, all of which improve efficiency and stability of the device, and also reduce hysteretic behavior. In this paper, the applications of fullerene materials in different layers of PSCs are systematically reviewed. And the basic rules of device performance improvement by decorating the structure of fullerene materials are also summed up. All these results are of great significance to promote the application of fullerene materials in perovskite solar cells.

Key words: solar energy, fullerenes, electronic materials, photon conversion efficiency, stability
