Description

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.

This document outlines the critical environmental and processing constraints for methylammonium thiocyanate (MASCN). The material requires strict protection from light, moisture, and oxygen to prevent deliquescence and hydrolysis that degrade precursor stoichiometry.

  • Inert Atmosphere Glovebox Requirement: Handle the powder within an inert-atmosphere glovebox with H2O < 1 ppm and O2 < 1 ppm to avoid moisture and oxygen exposure.
  • Light-Sensitive Storage: Store the material in light-protective packaging and a dark environment to prevent photodegradation.
  • Moisture Prevention: Tighten the container cap immediately after each use and transfer to a desiccated storage environment to prevent moisture ingress.
  • Incompatible Substances: Do not store the compound together with strong oxidizing agents or acidic reagents to avoid hazardous reactions.
  • Solvent Compatibility: The compound is freely soluble in water, ethanol, liquid ammonia, acetone, pyridine, and liquid sulfur dioxide for precursor solution formulation.

This procedure describes the safe handling and storage of methylammonium thiocyanate for perovskite precursor preparation. Proper glovebox usage and moisture control are essential to maintain material integrity.

Required Equipment: Inert-Atmosphere Glovebox, Light-Protective Storage Container, Desiccator, Protective Gloves

  1. Transfer to Glovebox
    Transfer the sealed container to an inert-atmosphere glovebox before opening to prevent moisture exposure.
  2. Weigh Material
    Weigh the required amount of powder inside the glovebox using a clean spatula and container.
  3. Reseal Container
    Tighten the container cap securely immediately after use to prevent moisture ingress from ambient air.
  4. Store Material
    Store the material in a light-protected, desiccated environment at room temperature, away from oxidizing agents and acids.

How does the crystallization retardation effect of MASCN impact the processing time for perovskite thin films?

The thiocyanate anion in MASCN retards perovskite crystallization to promote controlled nucleation and growth, which can increase processing time compared to conventional films. However, this trade-off yields larger grain sizes, reduced grain boundary density, and fewer internal defects, ultimately enhancing charge carrier mobility and power conversion efficiency.

What deposition techniques are compatible with MASCN as a perovskite crystallization additive?

MASCN is compatible with both one-step and two-step deposition protocols for perovskite thin films. It is specifically designed for spin-coating and precursor solution blending preparation techniques, making it suitable for standard laboratory fabrication of photovoltaic devices and photodetectors.

What are the critical storage conditions required to maintain methylammonium thiocyanate integrity?

Methylammonium thiocyanate must be stored in a light-protected, dry, sealed container at room temperature to prevent photodegradation and moisture ingress. It is hygroscopic and light-sensitive; exposure to atmospheric moisture causes deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. Handling should be performed in an inert-atmosphere glovebox with H2O < 1 ppm and O2 < 1 ppm.

This 99% purity Methylammonium Thiocyanate (MASCN) additive modulates perovskite crystallization kinetics to promote larger grain sizes and reduce internal film defects, enhancing charge carrier mobility and power conversion efficiency in solar cells. However, its extreme hygroscopicity and light sensitivity demand storage under inert, dry, light-protected conditions and glovebox handling during solution preparation.

Trade-offs

  • Hygroscopic and light-sensitive stability: The compound is hygroscopic and light-sensitive; exposure to atmospheric moisture causes deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. Storage must be light-protected, dry, and sealed at room temperature, with immediate transfer to a desiccated environment upon receipt.
  • Requires inert-atmosphere glovebox handling: During precursor solution preparation, the white powder must be handled within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm) to prevent moisture ingress. The container must be tightened immediately after each use to maintain material integrity.
