Spiro-OMeTAD sublimed grade

  • Spiro-OMeTAD (spiro meotad) is one of the most studied and applicable hole transport layer (HTL) materials due to its ease of implementation and high performance in organic-inorganic electronic devices. Borun New Material Spiro-OMeTAD provide high glass transition temperature (Tg), morphological stability, and ease of processing, while maintaining good electronic properties. spiro-ometad has been widely used in solid-state dye-sensitized solar cells (ssDSSCs), organic light-emitting diodes (OLEDs), perovskite solar cells (PSCs), and polymer-based organic solar cells (OSCs).

  • High-purity (>99%) Spiro-OMeTAD, Borun New Material a high performance HTL material
    Due to its simple implementation and excellent performance in organic-inorganic electrical devices, Borun New Material Spiro MeOTAD (Spiro-OMeTAD) is one of the most researched and useful hole transport layer materials (HTL). High glass transition temperature (Tg), morphological stability, and ease of processing are all features of the spiro-linked molecule while good electrical properties are maintained. Spiro-OMeTAD has been utilized extensively in perovskite solar cells (PSCs), solid-state dye-sensitized solar cells (ssDSSC), organic light-emitting diodes (OLED), and polymer-based organic solar cells (OSCs).

  • Talking about Borun New Material understanding of organic transport layer material Spiro-OMeTAD sublimed grade
    Borun New Material reason why organic-inorganic hybrid perovskite materials take the edge of the word "organic" is that the components contain methylammonium and formamidine ions. Using the word "organic" to describe lead-halide perovskite materials is inaccurate, because the A-site component of perovskites does not involve any organic-related properties other than the requirements for ionic radius. But if the word organic/inorganic hybrid is used to describe the device of perovskite solar cell, it is very suitable. Because the efficiency of perovskite solar cells is so high and the development is so fast, it is really inseparable from the blessing of organic semiconductor materials. Whether it is spiro-OMeTAD in upright nip devices or PTAA in inverted pin devices (of course there are many other excellent organic semiconductor materials), Borun New Material are very important and even indispensable organic transport materials. Taking spiro meotad as an example, it was the birth of the first all-solid-state perovskite solar cell based on spiro meotad in 2012 that ignited the engine for the rapid development of perovskite. Even with efficiencies approaching 26%.

    First of all, the spiro meotad is amorphous. Of course, this is based on the consideration of film formation. The designer deliberately designed a molecular structure that is not easy to crystallize. However, the lack of crystallization leads to poor contact between molecules and obstacles to the transfer of electrons, so its own conductivity and mobility are very low, and additional doping is required to improve the electrical properties of the material. There are really a lot of literature on the selection and various attempts of spiro meotad dopants. Generally speaking, there are the following four strategies: one is a relatively early strategy is to add oxidant to the precursor solution, A part of the spiro meotad is oxidized and charged to improve its conductivity and mobility; the second is to add lewis acid or protonic acid to the spiro meotad to polarize Borun New Material spiro-ometad; the third is to directly pre-synthesize the salt of the spiro meotad for use; the fourth is the most The most commonly used and most effective method is by doping LiTFSI (lithium bis-trifluoromethanesulfonimide) and TBP (tert-butylpyridine), followed by indirect slow oxidation by oxygen.
