Two org. dyes with the general structure donor-conjugated chain-acceptor (D-π-A) were studied as sensitizers for nanocryst. TiO2 solar cells. The electron donor and acceptor groups were pyrrolidine and cyano acrylic acid, resp. The conjugated chain of 2-cy ...
Org. chromophores were synthesized to approach optimal energy level compn. in the TiO2-dye-iodide/triiodide system in the dye-sensitized solar cells. HOMO and LUMO energy level tuning is achieved by varying the conjugation between the triphenylamine donor ...
The P1- or C343-sensitized NiO photocathodes for p-DSSCs were optimized to obtain substantial current from thin films prepd. in two steps rather than one. These films are capable of adsorbing more dye, in comparison to one step films with the same thicknes ...
High incident photon-to-current conversion efficiency of p-type dye-sensitized solar cells are based on transparent NiO films and org. chromophores [4-(bis-[4-[5-(2,2-dicyanovinyl)thiophene-2-yl]phenyl)amino]benzoic acid] and [4-(bis[4'-(2,2-dicyanovinyl)b ...
