Photo-sensitization of ZnS nanoparticles with renowned ruthenium dyes N3, N719 and Z907 for application in solid state dye sensitized solar cells: A comparative study

Fitting of the LUMO of ruthenium dyes in between P3HT and ZnS nanoparticles builds cascade type energy levels in these hybrid systems and result in enhanced charge transfer, reduced charge recombination and improved efficiency of solar cells.93
