Test of different sensitizing dyes in dye-sensitized solar cells based on Nb2O5 photoanodes
High-performance dyes routinely employed in TiO2-based dye-sensitized solar
cells (DSSCs) were tested in cells assembled using Nb2O5 nanostructure-based photoanodes.
The sensitizers were chosen among both metal-complex (two Ru-based, N749 and C106, and one
Zn-based dye, DNF12) and metal-free organic dyes (DNF01, DNF11 and DNF15). Two different
sensitization processes were performed: the one commonly used for TiO2 photoanodes, and a new
process relying on high pressure by autoclavation. The assembled cells were characterized by current
