Evolution of organometal halide solar cells

Publication date: Available online 2 March 2018 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Jotaro Nakazaki, Hiroshi Segawa Emerging organometal halide solar cells have attracted wide attention as “perovskite solar cells (PSCs)” from very many researchers, and the related articles more than 4,000 have been published to date. The power conversion efficiency (PCE) over 22% was achieved within a few years from the advent of the PSCs. In this review article, publications about the PSCs were summarized along their ‘submitted date’, to record the course of the progress. At the first stage, the PSCs were established as nano-structured solar cells. The efficiency up to 15% attracted the researchers in dye-sensitized solar cells and organic thin-film solar cells. After the appearance of planar hetero-junction type PSCs, the power generation mechanism has been argued. Around that time, several issues arose, such as I–V hysteresis and chloride contents. Although there were several severe comments about these issues, the developments of the PSCs progressed steadily, then efficiencies over 20% were reported. At present, the highest PCE in published papers is 22.6%, and the NREL chart records 22.7%. The development history of the PSCs is summarized in this review. Graphical abstract
