一步法热分解制备染料敏化太阳能电池pt对电极
Keywords: 材料合成与加工工艺,tio2纳米管阵列,pt对电极,染料敏化太阳能电池,热分解,光电性能
Abstract:
？用旋涂热分解前驱h2ptcl66h2o溶液制备pt/fto对电极,研究了旋涂退火次数对pt/fto对电极的载铂量、透光率和组装的染料敏化太阳能电池光电性能的影响。结果表明,用5次旋涂退火的对电极组装的电池具有最佳的能量转换效率(6.78%),高于用传统的磁控溅射对电极组装的电池。基于在最佳光电性能情况下对电极的旋涂次数和载pt量,进一步优化h2ptcl6?6h2o前驱液的浓度和使用体积。采用一步滴涂退火处理,得到了具有高透光性、低载pt量和高的组装电池效率的pt/fto对电极。用此一步法制备的pt/fto对电极,组装成的电池能量转换效率达到6.92%。
