Due to the high purity of the methylammonium iodide (99.99%), it should be noted that its solubility is reduced within dimethyl formamide and dimethyl sulfoxide. This reduced solubility is due to the removal of trace amounts of residual hydroiodic acid (HI) used during the synthesis and purification of the material. This can potentially have an impact upon the performance of solar cells leading to a reduction in maximum power conversion efficiency achievable. Adding fixed concentrations of hydroiodic acid to perovskite solutions can allow for the improvement of device metrics. Using high-purity precursor materials allows for accurate addition of amounts of hydroiodic acid giving higher reproducibility to experiments. It is recommended that between 1% and 10% hydroiodic acid is used with high-purity methylammonium iodide to achieve optimal device performance. The amount required depends on the precursors used, solution concentration, solvent used, and processing environment. Therefore, this will need to be adjusted for each individual laboratory and process. Application For simpler ink fabrication, it is recommended that the lower-purity methylammonium iodide (>98%) is used.

Uses Methylammonium iodide can be used as a precursor in combination with lead iodide to change the morphology of the resulting perovskite materials. Perovskite materials can further be utilized in the fabrication of alternative energy devices such as light emitting diodes (LEDs), and perovskite solar cells (PSCs). Uses Organohalide based perovskites have emerged as an important class of material for solar cell applications. Our perovskites precursors with extremely low water contents are useful for synthesizing mixed cation or anion perovskites needed for the optimization of the band gap, carrier diffusion length and power conversion efficiency of perovskites based solar cells.

Methylammonium Iodide (MAI; CAS No: 14965-49-2) is one of the most common precursors used in the preparation
of perovskite-based opto-electronic systems, including perovskite solar cells (Nath et al., 2022). Since the seminal work
by Kojima et al (2009) which demonstrated the use of the organolead halide perovskite CH3NH3PbI3 as a photoactive
material in solar cells, methylammonium lead triiodide perovskites have been extensively studied. Recent work has provided
valuable insights into their properties and optoelectronic performance (Reichert et al., 2020). MAI has also been recently used
in the precursor solution of an all-perovskite tandem solar cell (Lin et al., 2022). With a purity level > 99.99%, extremely low
moisture content and batch-to-batch reproducibility, Borun New Material - ChemBorun' Methylammonium Iodide is ultra-pure
for consistent results and superior performance. MAI is a free flowing powder, snow white in appearance. Borun New
Material - ChemBorun can provide g to kg quantities. Kojima, A., Teshima, K., Shirai, Y., Miyasaka, T., 2009. Organometal
