P2O5-ZnO-SiO2-R2O glass frit materials for hermetic sealing of dye-sensitized solar cells

Abstract

P2O5-ZnO-SiO2-R2O glasses were synthesized as a sealing material for large scale dye-sensitized solar cells (DSSC). Compositional effects of P2O5 and ZnO were examined by varying their contents. Their viscosity and glass stability at sintering temperatures of less than 550oC were examined by flow button test. Glass transition temperature and structural change upon compositional change were investigated. Chemical stability against electrolyte was also examined by immersing the glasses in the electrolyte for 72 h at 85°C.
