Tin(IV) oxide, 15% in water, colloidal, CAS: 18282-10-5

In perovskite solar cells (PSCs), tin dioxide (SnO2) is often employed as an electron transport layer (ETL) due to its excellent electron mobility and high transparency. Its function is to facilitate the efficient transport of photogenerated electrons from the perovskite layer to the external circuit, while also blocking holes, thereby improving the overall efficiency and stability of the solar cell. Using an aqueous solution of SnO2 can provide advantages such as ease of deposition, reduced toxicity, and environmental compatibility. This is particularly significant for scaling up the manufacturing process and aligns well with the sustainability goals often associated with renewable energy technologies like perovskite solar cells. This product, SVS01, developed by Saule S.A., is specifically optimized for compatibility with FAPbI3, ensuring excellent performance when used in conjunction with this material. Its tailored formulation enhances efficiency and reliability, making it an ideal choice for advanced perovskite applications.
