Abstract

Monodispersed ZnO nanoparticles have been synthesised in ethylene glycol medium using zinc acetate and sodium hydroxide at room temperature through ultrasonic treatment. The monodispersed ZnO nanoparticles were characterized by XRD, TEM, SEM, and optical spectroscopy. The results indicate that ZnO shows the hexagonal wurtzite structure having 8 nm average particle size with the band gap of 3.93 eV. ZnO nanoparticles blended with P3HT show the improvement in the interchains and intrachains ordering as compared to pure P3HT. The power conversion efficiency of P3HT/ZnO solar cell is found to be 0.88%, which is comparable with the result obtained by other researchers.

摘要

在室温下，通过超声处理，在乙二醇介质中使用醋酸锌和氢氧化钠合成了单分散的ZnO纳米颗粒。通过X射线衍射（XRD）、透射电子显微镜（TEM）、扫描电子显微镜（SEM）和光谱对单分散的ZnO纳米颗粒进行了表征。结果表明，ZnO呈现六方纤锌矿结构，平均粒径为8 nm，带隙为3.93 eV。与纯聚3-己基噻吩（P3HT）相比，与P3HT混合的ZnO纳米颗粒在链间和链内有序性方面有所改善。发现P3HT/ZnO太阳能电池的功率转换效率为0.88%，这与其他研究人员得到的结果相当。
