In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 3939-23-9, name is 3-Bromo-10H-phenothiazine, introducing its new discovery. name: 3-Bromo-10H-phenothiazine
New banana shaped A?D?pi?D?A type organic dyes containing two anchoring groups for high performance dye-sensitized solar cells
Two new bent A?D?pi?D?A type organic dyes (MA-1 and MA-2) consisting of carbazole and phenothiazine moieties as electron donors with 2,1,3-benzothiadiazole as a pi-linker with two end-anchoring groups are designed, synthesized and tested in DSSCs. The photophysical and electrochemical properties of the dyes are investigated in detail. Incorporation of phenothiazine unit in MA-2 resulted in high HOMO level (0.62?V vs. NHE), with a red shift in absorption maxima and broadening of the absorption spectrum. Under standard global AM 1.5 solar conditions, the MA-2 sensitized solar cells exhibited a short circuit photocurrent density of 13.1?mA?cm?2, an open-circuit voltage of 0.73?V, a fill factor of 0.72, corresponding to an overall conversion efficiency of 6.87%. Such design and development of molecular dyes are useful for improving the overall efficiency of DSSCs.
