The product, Factory Supply spiro-Ometad with CAS number 207739-72-8, is a well - known organic semiconductor material in the market. CAS number is a unique identifier for chemical substances, which helps to accurately distinguish this product from other similar substances.
Physically, spiro - Ometad usually appears as a solid powder. Its molecular formula is (C_{81}H_{68}N_4O_8), and it has a relatively high molecular weight. This product is known for its excellent hole - transporting properties. It has a good solubility in some common organic solvents, which makes it suitable for solution - processing techniques.
Factory Supply spiro - Ometad is mainly used in the field of perovskite solar cells. In perovskite solar cells, it serves as a hole - transporting material (HTM). The efficient hole - transporting ability of spiro - Ometad allows it to quickly extract and transport holes generated in the perovskite layer to the electrode, which is crucial for improving the photoelectric conversion efficiency of the solar cell.
Beyond solar cells, spiro - Ometad can also be used in organic light - emitting diodes (OLEDs). In OLEDs, it helps in the efficient transfer of holes to the emissive layer, improving the device's luminous efficiency and performance.
When using Factory Supply spiro - Ometad, first, it needs to be dissolved in a suitable organic solvent. Commonly used solvents include chlorobenzene or toluene. The concentration of the solution should be carefully controlled according to the specific application requirements. Usually, a concentration in the range of 70 - 90 mg/mL is often used in perovskite solar cell fabrication.
After preparing the solution, it can be deposited onto the substrate using solution - processing techniques such as spin - coating. During spin - coating, parameters such as spin speed and spin time need to be optimized to obtain a uniform and thin film. After the film is formed, it may require annealing treatment at an appropriate temperature to further improve its performance.
In a perovskite solar cell research project, a research team used Factory Supply spiro - Ometad as the hole - transporting material. They prepared a 80 mg/mL spiro - Ometad solution in chlorobenzene. By spin - coating the solution onto the perovskite layer at a spin speed of 4000 rpm for 30 seconds and then annealing the film at 100°C for 10 minutes, they obtained a high - quality hole - transporting layer.
The fabricated perovskite solar cell showed a significant improvement in photoelectric conversion efficiency. The initial efficiency of the solar cell without using spiro - Ometad was only about 12%. After using this high - quality spiro - Ometad hole - transporting layer, the efficiency increased to 18%. This case clearly demonstrates the important role of Factory Supply spiro - Ometad in improving the performance of perovskite solar cells.
