With the fast progress of solar cells efficiency in the last few years, hybrid organic/inorganic metal halide perovskite solar cells (PSCs) became a center point of research for a lot of solar cell researchers. The perovskite materials show different merits like longer carrier diffusion lengths, wider-tunable bandgap in addition to higher potential of light absorption. The higher efficiency together with the cheaper fabrication methods makes perovskite solar cells comparable with Si-based solar cells. The PSCs efficiency has a remarkable increase from 3.8% to more than 25.2 %. There is a great need for an overall understanding of the function of each of the solar cell components and its impact on cell efficiency and performance. This review starts with the discussion of perovskite structure (electronic and crystal) based on recent research. The working principles and the fabrication methods of PSCs are also introduced. PSCs evaluation is also analyzed and presented with more details regarding modelling approaches and simulation tools.
