发布时间：2018-12-11 21:23
【摘要】：采用电沉积法制备出ZnO致密纳米颗粒膜和不同尺寸的纳米棒阵列。通过在ZnO上旋涂p型聚合物聚3-己基噻酚(P3HT)与n型富勒烯衍生物[6,6]-苯基-C61丁酸甲酯(PCBM)的混合物,并蒸镀金属Ag,制备出不同结构的杂化太阳能电池。通过扫描电镜、X射线衍射、光致发光和模拟太阳光光电性能测试,对ZnO的生长条件、晶体形貌及缺陷与太阳能电池性能之间的关系进行了系统研究。结果表明,ZnO的形貌和晶体缺陷的分布对杂化太阳能电池有重要影响,避免共混聚合物与ZnO缺陷聚集区的直接接触可有效消除电流泄漏。在电池结构方面,与ZnO纳米阵列块状结构杂化太阳能电池相比,共形结构的杂化太阳能电池可有效缩短空穴到金属电极的传输距离,增大聚合物与金属电极的接触面积,光电转换效率可提升64%~101%。
[Abstract]:ZnO dense nanocrystalline films and nanorod arrays of different sizes were prepared by electrodeposition. Hybrid solar cells with different structures were prepared by spin-coating p-type polymer poly (3-hexylthiophenol) (P3HT) on ZnO and n-type fullerene derivative [6O6] -phenyl-C61 butyrate (PCBM). The hybrid solar cells were prepared by vaporizing metal Ag,. By means of scanning electron microscope, X-ray diffraction, photoluminescence and simulated solar photoelectricity, the relationship between the growth conditions, crystal morphology and defects of ZnO and the performance of solar cells was studied systematically. The results show that the morphology of ZnO and the distribution of crystal defects have an important effect on hybrid solar cells. Avoiding the direct contact between the blend polymer and the ZnO defect accumulation area can effectively eliminate the current leakage. In terms of cell structure, compared with ZnO nanoarray hybrid solar cells, conformal hybrid solar cells can effectively shorten the distance from hole to metal electrode and increase the contact area between polymer and metal electrode. Optoelectronic conversion efficiency can be increased by 64 / 101.
