摘　　要：Although the power conversion efficiency（PCE） of CH3 NH3 PbI3-based solar cells has achieved 22.1%,which is comparable to commercialized thin-film CdTe and Cu（In,Ga）Se2 solar cells, the long-term stability is the main obstacle for the commercialization of perovskite solar cells. Recent efforts have been made to explore alternative inorganic perovskites, which were assumed to have better stability than organic-inorganic hybrid CH3 NH3 PbI3. In this short review, we will keep up with experiments and summarize recent progresses of inorganic double halide perovskite, in particular to Cs2 AgBiBr6, Cs2 AgInCl6, Cs2 InBiBr6 and their family members. We will also share our opinions on the promise of such class of materials.Although the power conversion efficiency（PCE） of CH3 NH3 PbI3-based solar cells has achieved 22.1%,which is comparable to commercialized thin-film CdTe and Cu（In,Ga）Se2 solar cells, the long-term stability is the main obstacle for the commercialization of perovskite solar cells.
