The field of perovskite solar cells (PSCs) continues to evolve at a rapid pace, driven by the promise of high efficiencies and low manufacturing costs. At the heart of this technological advancement are the precursor materials that form these innovative devices. N-Butylammonium Iodide (BAI), identified by CAS No. 36945-08-1, is a key player in this arena, acting as a crucial organic spacer that significantly impacts the performance and stability of PSCs. As a prominent manufacturer and supplier of advanced chemical materials in China, we are proud to contribute to this progress by offering high-quality BAI.

The fundamental benefit of incorporating N-Butylammonium Iodide into perovskite precursor solutions lies in its ability to modify the perovskite crystal structure. As an organic spacer, BAI helps to create layered perovskite architectures, often referred to as 2D perovskites or Ruddlesden–Popper phases. While the direct addition of BAI can sometimes lead to increased film roughness, its strategic use is known to effectively hinder the growth of undesirable 3D-perovskite grains. This controlled crystallization process results in smoother, more uniform films which are essential for efficient charge carrier transport and collection in solar cells. This improvement in film morphology directly translates to enhanced power conversion efficiencies.

Beyond structural benefits, BAI is recognized for its role in improving the overall stability of perovskite devices. The hydrophobic nature of the n-butylammonium cation contributes to a more robust perovskite film, acting as a barrier against moisture ingress, which is a major cause of degradation in PSCs. This enhanced moisture resistance leads to improved operational stability and extended device lifetimes, making perovskite technology more viable for commercial applications. Researchers and manufacturers worldwide are seeking to buy n-butylammonium iodide to leverage these advantages.
