ABSTRACT: The
solar cells based on the emerging organic-inorganic hybrid halide perovskite is
progressing rapidly in the last decade, but the commercialization of the perovskite solar cells still faces significant
challenges. The major issues are the poor long-term stability and toxicity. In
light of this, materials design and screening of novel stable perovskites is
becoming an important research direction. In contrast to conventional trail-and-error
processes, materials genome techniques and high-throughput
calculations have been prevalently applied in this area and accelerated
materials discovery. In this talk, I will present a review that summarizes our
recent progress in this field, mainly focusing on four classes of perovskites including AM2+X3 halide single
perovskites, AM4+Y3
chalcogenide single perovskites,
A2M+M3+X6
halide double perovskites and A2M3+M5+Y6
chalcogenide double perovskites. The stability, electronic, optical, and
defect properties of these materials in terms of their applications as solar
cell absorbers are discussed.
