Z907 Dye

Product Code M2002A1
Price £103.00 ex. VAT

Z-907 dye, (cis-Ru(H2dcbpy)(dnbpy)(NCS)2, where the ligand H2dcbpy is 4,4′-dicarboxylic acid-2, 2′-bipyridine and dnbpy is 4,4′-dinonyl-2,2′-bipyridine, is amphiphilic nature while the introduction of the two hydrophobic alkyl chains on the bipyridyl ligand is critical to provide an insulating barrier to avoid charge carrier recombination and also help enhance thermal stability. 

It was reported that DSSC with Z907 and hexadecyl phosphonic acid adsorbing maintained 7% efficiency for as long as 1,000 hours ageing test at 80 oC [1].
