制备了玻璃/F掺杂SnO 2/TiO 2/La修饰或Zn掺杂Sb 2S 3/聚[（3-己基噻吩）-2，5-二基]/聚[3-（3-羧基丙基）噻吩-2，5-二基]/Au有机-无机杂化太阳能电池，并对其光伏性能进行了评价。使用La修饰的Sb 2S 3的混合太阳能电池的功率转换效率（PCE）的33%的改善相比，未修饰的Sb 2S 3，因为降低了在界面处的电阻，这是由阻抗分析证实。结果表明，添加的La在TiO 2和Sb 2S 3层之间发生了相分离和富集。而Zn掺杂使Sb_2S_3的晶粒尺寸从14 nm增大到25 nm。利用Zn掺杂的Sb 2S 3的混合太阳能电池获得了57%的PCE的提高。这一结果归因于有效地降低了体电阻。
Organic-inorganic hybrid solar cells composed of glass/F-doped SnO2/TiO2/La-decorated or Zn-doped Sb2S3/poly [(3-hexylthiophene)-2, 5-diyl]/poly [3-(3-carboxypropyl) thiophene-2, 5-diyl]/Au have been prepared and evaluated their photovoltaic performance. Using La-decorated Sb2S3 for hybrid solar cell resulted in 33% improvement of power conversion efficiency (PCE) as compared to that of the non-decorated Sb2S3 because of lowering the resistance at the interface, which was confirmed by the impedance analyses. It was found that the added La was phaseseparated and accumulated between the layers of TiO2 and Sb2S3. While doping of Zn into Sb2S3 resulted in the enlargement of the crystallite size of Sb2S3 from 14 nm to 25 nm. Utilization of Zndoped Sb2S3 for hybrid solar cell attained 57% enhancement of PCE. This result is ascribed to the effective lowering the bulkresistance.
