摘要
将H_3PW_(12)O_(40)(PW_(12))用电沉积法沉积在TiO_2纳米管薄膜上,得到PW_(12)-TiO_2纳米管复合薄膜,再将PW_(12)-TiO_2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PW_(12)修饰的TiO_2纳米管薄膜的光电转换效率达到3.62%,是未修饰TiO_2纳米管薄膜(0.36%)的10倍左右,说明在TiO_2纳米管薄膜光电转换时PW_(12)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TiO_2纳米管薄膜的光电转换效率。
Using electrodeposition method to compound a layer of H_3PW_（12）O_（40）（PW_（12））on TiO_2 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.
