    Abstract:

    Organic-inorganic hybrid perovskite solar cells are considered as one of the most promising third-generation photovoltaic technologies. After only a few years of research, the highest efficiency of perovskite solar cells has exceeded 22%. As the efficiency of perovskite solar cells has become closer to theoretical efficiency, researchers have turned their attention to the near-infrared bands that perovskite materials cannot effectively absorb, in order to further increase the efficiency. In this article, we review the research of combining up-conversion materials with perovskite solar cells in the past two years and classify them into more traditional methods and new methods. The traditional method is to use a relatively single NYF nanoparticle to dope the perovskite solar cell, utilize the up-conversion effect of rare earth ions, absorb the near infrared light, widen the absorption range of the perovskite, and thus enhance the performance of the solar cell. The new method is to add other ions or introduce heavily doped semiconductor materials to further enhance the performance of solar cells based on the traditional single use of rare earth ions. From the experimental results, both methods have achieved better performaces.
