摘　　要：采用N719作为染料,并对比采用I2、KI及分别添加叔丁基吡啶(TBP),1,2-二甲基-3-丙基咪唑碘盐(DMPⅡ)和Guanidine Thiocyanate(GUSCN)作为电解质,采用AB胶及光固化无影胶进行封装,以太阳光模拟器作为光源用电化学工作站测曲线数据,找出提高光电转换效率的条件。利用电化学工作站测试添加三种不同电解质的电池效率可知,添加TBP或是添加DMPⅡ和GUSCN的效率都比只含I2和KI的效率高,分别相对高6.75和50.28,且添加DMPⅡ和GUSCN后的效率比添加TBP的效率相对高40.77。封装方面根据染料敏化纳米晶太阳能电池的密封要求,当采用无影胶进行封装,密封性能、耐溶剂性较好,可能满足生产要求。N719 is chosen as dye, and electrolyte is I2 and KI, adding （TBP） and 1.2-Dimethyl-3-propylimidazolium iodide （DM- PII） ＆ Guanldine Thiocyanate （GUSCN）. We encapsulate with AB glue, shadowless light -cured rubber as sealant We use sunlight simulator as light source, and use electrochemistry workstation to measure curves and data. By comparison we get the condition for higher efficiency. With electrochemical testing the use of workstations which adds three different electrolyte battery efficiency, we can see that the efficiency adding TBP or add DMPII and GUSCN are higher than just adding the I2 with the KI, respectively 6. 75 percent and 50. 28 percent, and the efficiency adding DMPII and GUSCN are higher than adding TBP by 40. 77. According to the packaging area dye - sensitized nanocrystalline solar cell sealing requirements when using a trace of plastic encapsulation, sealing performance, solvent resistance are all very good, and shadowless light-curcd rubber may meet production requirements.
