This product category contains materials for perovskite solar cells optimized for deposition by evaporation techniques. The perovskite salts are of highest purity, >99.999 %, based on trace metal analysis, humidity levels <20 ppm and free from organic solvent residues. In comparison to conventional SAM Materials, the ones for evaporation are characterized by higher crystallinity and rigidity.
This class of materials can divided into two sub-groups as outlined below.
Salt for preparing engineered narrow bandgap perovskite materials using deposition by evaporation for increased efficiency. Dyenamo offers a high-purity FAI (specifications below); >99.999 % (grade 5N).
Salt for preparing engineered narrow bandgap perovskite materials using deposition by evaporation for increased efficiency. Dyenamo offers a high-purity FABr (specifications below); >99.999 % (grade 5N).
DN-X67 (CbzNaphPPA) is a highly crystalline SAM-type hole conductor, which is compatible with both wet spin coating and vacuum deposition techniques. Due to the high crystallinity obtained, highly ordered self-assembled multilayers can be formed on ITO substrates establishing excellent surface coverage for high performance and stability of perovskite solar cells (26.1% and 23.5% efficiencies have been shown in devices manufactured using spin-coating and thermal evaporation methods, respectively).
DN-X69 (PhCzPPA) belongs to the SAM HTM family as DN-X67 (CbzNaphPPA). Due to the high degree of crystallinity, this Dyenamo-developed DN-X69 is suitable for both vacuum and wet deposition techniques.
DN-X73 (DMA-Ph-PA) is a Dyenamo-designed highly crystalline SAM that can be used in thermal evaporation technology, as well as wet deposition processes, such as spin-coating. The high crystallinity obtained opens for deposition of highly ordered self-assembled multilayers with thorough surface coverage on e.g.for instance ITO substrates.
