FORMAMIDINIUM THIOCYANATE CH₃N₃S 99% FASCN

RESEARCH GRADE MATERIAL

Product Overview

Formamidinium Thiocyanate (CH₃N₃S, FASCN) is a formamidinium-based perovskite precursor additive with CH₃N₃S 99% purity FASCN, supplied as a white powder with a molecular weight of 89.14 g/mol. This compound functions as an effective perovskite crystallization modulator, where the thiocyanate anion regulates crystal nucleation and growth kinetics during thin film formation. By retarding crystallization, FASCN promotes larger grain sizes and reduces internal film defect density, directly enhancing charge carrier mobility and power conversion efficiency in formamidinium-based perovskite solar cells. The material exhibits excellent solubility in polar organic solvents and water, enabling versatile precursor solution formulation across multiple deposition protocols. 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

Thiocyanate-Mediated Crystallization Control for FA-Based Perovskites: The thiocyanate anion specifically modulates nucleation and growth kinetics in formamidinium-based perovskite systems, promoting larger grain sizes and reduced grain boundary density for enhanced charge transport compared to conventionally processed films.
Enhanced Carrier Mobility via Defect Density Reduction: By reducing internal film defect density through controlled crystallization, FASCN directly improves charge carrier mobility and suppresses non-radiative recombination, contributing to higher power conversion efficiency in completed photovoltaic devices.
Broad Solvent Compatibility for Versatile Processing: The compound is freely soluble in polar organic solvents and water, providing exceptional flexibility in precursor solution formulation across DMF, DMSO, and aqueous-based 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 formamidinium-based perovskite thin film preparation via spin-coating and solution blending. Grain size enhancement agent for reducing internal film defects and improving film morphology. Precursor solution additive for enhancing charge carrier mobility in FA-based perovskite solar cells. Compatible with one-step and two-step deposition protocols utilizing polar organic solvent systems. 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 5 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 formamidinium 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: Formamidinium 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 freely soluble in polar organic solvents and water. For detailed safety and handling information, consult the Safety Data Sheet prior to use.
