METHYLAMMONIUM THIOCYANATE C₂H₆N₂S 99% MASCN CAS 61540-63-4

RESEARCH GRADE MATERIAL

Product Overview

Methylammonium Thiocyanate (C₂H₆N₂S, MASCN, CAS 61540-63-4) is a specialized perovskite precursor additive with C₂H₆N₂S 99% purity MASCN, supplied as a white powder with a molecular weight of 90.15 g/mol. This compound functions as an effective perovskite crystallization additive, where the thiocyanate anion modulates perovskite crystallization kinetics, optimizes film grain size, and reduces internal film defects. The resulting improvement in film morphology directly enhances charge carrier mobility and power conversion efficiency in perovskite solar cells. The material exhibits broad solubility in water, ethanol, liquid ammonia, acetone, pyridine, and liquid sulfur dioxide, enabling versatile precursor solution formulation. Widely utilized in university and research institute laboratories for photovoltaic device and photodetector experimental research, this high-purity additive is compatible with solution spin-coating and precursor solution blending preparation techniques. Strict light-sensitive hygroscopic dry storage is required to maintain material integrity.

Key Features & Advantages

Effective Crystallization Kinetics Modulation: The thiocyanate anion retards perovskite crystallization, promoting controlled nucleation and growth that results in larger grain sizes, reduced grain boundary density, and fewer internal film defects compared to conventionally processed films.
Enhanced Carrier Mobility and Device Efficiency: By reducing internal film defects and optimizing grain morphology, MASCN additive treatment directly improves charge carrier mobility and suppresses non-radiative recombination, contributing to higher power conversion efficiency in completed photovoltaic devices.
Broad Solvent Compatibility: The compound is freely soluble in water, ethanol, liquid ammonia, acetone, pyridine, and liquid sulfur dioxide, providing exceptional flexibility in precursor solution formulation across a wide range of perovskite deposition protocols.
Ultra-High Purity Exceeding 99%: Refined to >99% purity with low batch impurity content, the additive introduces minimal extrinsic contamination during the crystallization modulation process, ensuring reproducible film quality across experimental batches.

APPLICATION SCOPE: Crystallization additive for perovskite thin film preparation via spin-coating and solution blending. Grain size optimization agent for reducing internal film defects and improving film morphology. Precursor solution additive for enhancing charge carrier mobility in perovskite solar cells. Compatible with one-step and two-step deposition protocols. Supports photovoltaic device and photodetector research in university and research institute laboratories where controlled crystallization and defect reduction are experimental priorities.

PACKAGING: This listing is for the 10 g specification. Other packaging weights are available upon custom request. Each package is sealed under inert atmosphere within light-protective packaging to prevent photodegradation and moisture ingress. The hygroscopic nature of methylammonium thiocyanate necessitates immediate transfer to a desiccated, light-protected storage environment upon receipt. For bulk quantities or custom packaging specifications, please contact us via email.

IMPORTANT NOTICE: Methylammonium thiocyanate is hygroscopic and light-sensitive. Tighten the container cap immediately after each use to prevent moisture ingress from ambient air. Wear protective gloves throughout all experimental procedures to avoid direct skin contact. Store in a light-protected, moisture-free environment; do not store together with strong oxidizing agents or acidic reagents. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. When preparing precursor solutions, handle the white powder within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm). The compound is soluble in water, ethanol, liquid ammonia, acetone, pyridine, and liquid SO₂. For detailed safety and handling information, consult the Safety Data Sheet prior to use.
