【摘要】 将H₃PW₁₂O₄₀(PW₁₂)用电沉积法沉积在TiO₂纳米管薄膜上,得到PW₁₂-TiO₂纳米管复合薄膜,再将PW₁₂-TiO₂纳米管复合薄膜组装成光伏电池,测定其光电转换效率。结果表明:用PW₁₂修饰的TiO₂纳米管薄膜的光电转换效率达到3.62%,是未修饰TiO₂纳米管薄膜（0.36%）的10倍左右,说明在TiO₂纳米管薄膜光电转换时PW₁₂能有效地抑制光生电子-空穴的复合,起到了储存和转移电子的作用,从而极大地提高了TiO₂纳米管薄膜的光电转换效率。更多还原

【Abstract】 Using electrodeposition method to compound a layer of H₃PW₁₂O₄₀(PW₁₂)on TiO₂ nanotube film for the purpose of modification and then assembled such compounded film into the PV cell and determined their photoelectric conversion efficiency.The experimental results showed that the conversion efficiency（3.62%）made 10 times more than that of the non-modified（0.36%）,meaning that such polyacid can effectively inhibit the compounding of PV electrons and holes and function to store and effectively converted the electrons,thus greatly enhancing the conversion efficiency.更多还原
