A series of octacarboxy-metallophthalocyanine dyes, i.e., MgOCPc, MnOCPc, FeOCPc and ZnOCPc with different central metal ions were designed and synthesized by microwave irradiation. The effects of the introduction of different metal ions with variant 3d orbitals (3d0, 3d5, 3d6, and 3d10, respectively) in the centre of the phthalocyanine rings on the thermal, photophysical, and electrochemical properties of octacarboxy-metallophthalocyanines were characterized and evaluated in details. The results showed that ZnOCPc and MgOCPc with closed-shell metal ions and FeOCPc with an open-shell metal ion had excellent thermal property. However, MnOCPc with a half-full-shell metal ion had a lowest decomposition temperature and largest Q band red shifts. By theoretical calculation, the energy gaps of MgOCPc, MnOCPc, FeOCPc and ZnOCPc were 0.11, 0.10, 0.20 and 0.22V, respectively. Applied in TiO2 nanocrystalline dye-sensitized solar cells (DSSC), the photovoltaic properties of the four dyes were obtained under AM1.5 irradiation (100 mW cm-2).

To ensure long-term stable dye-sensitized solar cells (DSCs) and modules, a hermetic sealing is required. This research investigates the chemical stability ofI-/I3-redox electrolyte and four different glass frits (GFs). Sintered GF layers were openly exposed to nonaqueous redox electrolyte and redox electrolyte with 1, 5, and 10 wt% H2O in thin, encapsulated cells. The change inI3−absorbance was assigned to a reaction between the GF andI-/I3-electrolyte and was used to evaluate the chemical stability of the different GFs. TheI3−absorbance change was monitored over 100 days. Two out of the four GFs were unstable when H2O was added to the redox electrolyte. The H2O caused metal ion leaching which was determined from EDX analysis of the inorganic remains of electrolyte samples. A GF based on Bi2O3–SiO2–B2O3with low bond strength leached bismuth into electrolyte and formed theBiI3-complex. A ZnO–SiO2–Al2O3-based GF also became unstable when H2O was added to the redox electrolyte. Leaching of zinc ions due to exchange with H+resulted in the formation of a zinc-iodine compound which causedI3−depletion. By applying the test design to different types of GFs, the material suitability in the DSC working environment was investigated.
