【摘要】 将纳米TiO2颗粒以电泳沉积法披覆于导电玻璃上,同时整合光电极、反电极、电解质及染料制备出染料敏化太阳能电池.首先将TiO2纳米颗粒与异丙醇所混合的电泳悬浮液通过电泳技术沉积出适当厚度的多层膜结构;精确控制制程中的电流、电压与沉积时间而获得单层厚度为3.3μm的TiO2薄膜.此多层膜通过低温烧结增加其致密性及染料披覆效果.最后将此多层薄膜作为工作电极,封装成染料敏化太阳能电池,经由I-V曲线检测结果显示,所制染料敏化太阳能电池的光电转换效率为5.29%,且这种染料敏化太阳能电池的制造成本十分低廉.更多还原

【Abstract】 This research adopts TiO2 nanoparticles to prepare the photo electrode in DSSC.The TiO2 nanoparticles produced are coated on conducting glass by electrophoresis,and then combined with dye,electrolyte,Pt counter electrode and conducting glass to produce dye-sensitized solar cells.Through the electrophoretic technique,a multilayer film at an appropriate thickness is deposited in the suspension mixed by TiO2 nanoparticles and isopropanol.In the process,electric current,voltage,and number of times of deposition are well controlled to obtain a single TiO2 film with thickness of 3.3 μm.After sintering under low temperature,the prepared multilayer TiO2 film with very good compactness can increase the effects of dye coating.In addition,the dye-sensitized solar cells produced are exposed to metal halide lamp,and their electro-optical conversion efficiency is measured.The I-V curve of the produced dye-sensitized solar cells shows that they have high electro-optical conversion efficiency of 5.29%,and their manufacturing cost is very low.更多还原
