Research of PbS/CdS Quantum Dots on TiO2 Nanotube Photovoltaic Effect
【摘要】 用CdS包覆PbS,起到对PbS外层保护和缓冲作用,以降低电解质对PbS的腐蚀,再制备成CdS/PbS/TiO2纳米管复合薄膜光电极,用其组装成光伏电池,测定其光电转换效率,结果表明:CdS/PbS/TiO2纳米管复合薄膜光电极的光电转换效率为3.95%,分别是单一量子点敏化PbS/TiO2、CdS/TiO2纳米管光电极光电转换效率的3.1倍和2.4倍.说明CdS和PbS带隙的有效匹配更有利于光电子的注入和空穴的再生,并减少了电子-空穴的复合,起到了PbS/CdS的共敏化作用,极大地提高了CdS/PbS/TiO2纳米管复合电极的光电转换效率.
【Abstract】 We use the CdS coated to protected and cushioned PbS. Then assemble such compounded film intothe PV cell and determine their photoelectric conversion efficiency. Our experiment result shows that the CdS/PbS/TiO2 nanotubes photoelectric conversion efficiency of 3.95%, are single quantum dots sensitized PbS/TiO2, CdS/TiO2 nanotubes photoelectric aurora electricity conversion efficiency of 3.1 times and 2.4 times. CdS effective match-ing PbS band gap more conducive to optoelectronic injection and cavitation of regeneration, and effectively inhibitthe compounding of PV electrons and holes, The PbS/CdS sensitization effect, play a PbS/CdS sensitization effect,greatly enhancing the conversion efficiency.
