LEAD-FREE SEALING COMPOSITION FOR A DYE-SENSITIZED SOLAR CELL PANEL CAPABLE OF DYE-SENSITIZING AT THE LOW TEMPERATURE WITHOUT USING A LOT OF LOW EXPANSION FIREPROOF CERAMIC POWDER

摘要

PURPOSE: A lead-free sealing composition for a dye-sensitized solar cell panel is provided to prevent the environmental contamination by a lead component, and to secure the high mobility and durability.;CONSTITUTION: A lead-free sealing composition for a dye-sensitized solar cell panel contains 30~45mol% of Bi_2O_3, 13~35mol% of znO, 15~35mol% of B_2O_3, 0.1~3mol% of al_2O_3 0, 0~5mol% of R_2O and 0~5mol% of R`O. The composition also includes 60~90wt% of base glass and a low-expandable ceramic filler. The R_2O is selected from the group consisting of Li_2O, Na_2O, K_2O and Cs_2O. The R`O is selected from the group consisting of MgO, BaO, CaO and SrO.;COPYRIGHT KIPO 2010
