Future photovoltaic systems require low-cost fabrication process and high power conversion efficiency for widespread use in the world. Recently, inorganic-organic (I/O) hybrid halide perovskite materials have attracted a great deal of attention in photovoltaic applications. The hybrid halide materials with a perovskite crystal structure are self-assembly formed by direct reaction between organic halides and inorganic metal halides, resulting in fabricating the solid-state solar cells through low-cost solution process. In addition, their performance surprisingly exceeded 20 % which value has been accepted to commercialize if their life-time is ensured. The high performance is mainly attributed to developments of device architecture, fabrication process, and manipulation of perovskite materials. In this talk, compositional and fabrication engineering for perovskite materials will be introduced for the high performance. |
