The intergovernmental panel on climate change has warned about the global temperature that will rise by 4 to 5.8 °C by the end of the century; carbon dioxide (CO 2 ) too will to increase up to 1099 ppm by 2100s. [2] All this will severely impact the environment in terms of melting glaciers, rising sea levels, global warming, etc. This has led the research focus on renewable energy alternative sources such as, solar energy, wind energy, geothermal, etc., in which solar energy is an abundant and attractive for photovoltaic (PV) application. In PV, silicon (polycrystalline, monocrystalline, and amorphous), copper indium gallium (di) selenide (CIGS), gallium arsenide (GaAs), and cadmium telluride (CdTe), heterojunction with intrinsic thinlayer based PV technologies are being used worldwide in which silicon-waferbased solar cells account for about 94% of the total production. [3][4][5][6][7] However, the high cost of inorganic photovoltaic has prevented these technologies from having a significant impact on global energy production. The main disadvantage of these solar cell technologies is the high purity environment needed for device handling and processing. [8,9] The energy and cost required for the material processing and device fabrication are comparatively high, which limits its effectiveness as an alternate energy source. The perovskite solar cells (PSCs) and dye-sensitized solar cells (DSSCs) are also being studied as potential alternatives. [10,11] DSSCs could be

In this work, the growth of formamidinium (FA) based mixed halide perovskite single-crystal via inverse temperature crystallization method is investigated and characterized to detect its photosensitive properties. The structural characterization...
