Stability of Dye Sensitized Solar Cells with Glass Frit Sealant
Glass frit sealant was prepared under different conditions,including the ratios of each composition,grinding method of the sealants domma drying temperature,and sintering process.When the ratio of glass frit,terpineol and ethyl cellulose was fixed at 5∶4∶1,a uniform sealant film without any pore or crack was obtained.The rates of weight loss for the cells filled with water and electrolyte sealed with the glass frit films were investigated.The drying temperature of 25℃ and sintering at 560℃ with temperature gradients led to the smallest rate of weight loss both for water and electrolyte.Furthermore,the optimized sealant was used into solar cells,which exhibited best stability by retaining 80% of their initial conversion efficiency,accompanying an electrolyte leakage rate as small as 0.12% after 800 hours tracking test at room temperature.
