1,4-双二茂铁噻吩/纳米二氧化锡异质结光伏性质研究

Photovoltage Property about Heterojunction Composite Film with 1,4-bis(ferrocene) Thiophene and SnO_2 Nanoparticles

运用LB技术制备了1,4-双二茂铁噻吩与纳米二氧化锡复合膜异质结.用AFM和XRD分别表征了纳米二氧化锡和异质结的成膜特性以及二氧化锡的物相结构;用紫外可见吸收光谱和表面光电压谱(surfacephotovo-ltagespectra,SPS)对其光吸收和光伏性质进行了研究,发现复合膜异质结在紫外可见光区(300～550nm)有很好的光伏性能,相对于单一薄膜材料的光伏响应范围有一定程度的拓展,而且响应强度也有较大提高.

In this paper, we successfully fabricated a novel heterojunction composite film composed of 1,4-bis (ferrocene) thiophene and SnO2 nanoparticles. The morphology and microstructure have been investigated by AFM and XRD. Their Optical and photovoltage properties were also studied using UV-Vis spectra and surface photovoltage spectra(SPS). The results indicate that the novel heterojunction composite film has a higher photovoltage response in a wider region of 300 similar to 550 nm than the single film.
