SAM Formation Reagent with Three Carboxylic Acid Moieties as Anchors: 3CATAT-C3
Product
3CATAT-C3 is commercialized under the instruction of Professor Atsushi Wakamiya of Kyoto University, and under an invention license by EneCoat Technologies Co., Ltd.
Advantages
- Efficient charge recovery from the perovskite layer
- Superior wettability for large area fabrication
- Applicable to co-depositon process (Number of processes can be reduced.)
- Available with high purity / in large quantities
Application
3CATAT-C3 is a high-performance hole-collecting material (HCM) for inverted perovskite solar cells. The partially exposed carboxy groups form a monolayer with high wettability, making it suitable for perovskite layer deposition. By coating the mixture of 3CATAT-C3 with a perovskite precursor on ITO, both a hole-collecting layer and a perovskite layer can be fabricated simultaneously.1)
3CATAT-C3 (Product No. C4192) shows comparable performance to 3PATAT-C3 (Product No. P3172), a high-performance hole recovery material. 3CATAT-C3 shows similar performance in the co-deposition method as in the layer by layer deposition method.
