Abstract: A photosensitive organic dye is adapted to be used in a photoelectric converting device such as a dye-sensitized solar cell. The photosensitive organic dye having a structural formula (I): where, Aryl1 represents substituted or unsubstituted aryl with one or more aromatic rings, NR2R3 represents a substituted electron-donating group, wherein N represents a nitrogen atom, and R2 and R3 independently represent identical or different substituted or unsubstituted hydrocarbon groups, L represents an optional linker unit, and A represents an electron-withdrawing group.

Abstract: A photosensitive porphyrin-based dye is adapted to be used in a photoelectric converting device such as a dye-sensitized solar cell. The photosensitive porphyrin-based dye has a porphyrin center, at least one electron donor unit, at least one electron acceptor unit and an optional blocker unit wherein the units are directly connected to the porphyrin center or connected to the porphyrin center via ethynyl-bridges. The photosensitive porphyrin-based dye having a structural formula (I): where D represents an electron donor unit, A represents an electron acceptor unit and P represents a blocker unit.

Abstract: The present invention relates to zinc porphyrin-based photosensitive dyes, specifically to zinc porphyrin-based photosensitive dyes with green transparency. The photosensitive dyes exhibit high push-pull ability in the zinc porphyrin-based structure, higher absorption and power conversion efficiency. The photosensitive dyes are used in the manufacture of dye-sensitive solar cells.
