在本工作中,我们制备了一种多孔的有机/无机复合电子传输层(P-ZnO),并将其成功用于反向有机太阳能电池中.P-ZnO不仅拥有适宜的功函,且可形成较大欧姆接触面积的独特表面,有利于器件中的电荷提取.与ZnO基器件相比,P-ZnO基器件的活性层具有增强的光陷阱效应.在PBDB-T/DTPPSe-2F,PM6/Y6和PTB7-Th/PC71BM三个活性层体系中,基于P-ZnO的器件都可实现8%增幅的效率提升.尤其是P-ZnO/PBDB-T/DTPPSe-2F的未封装器件无论在氮气还是空气氛围下,均表现出良好的长期稳定性.在空气中制备的P-ZnO/PBDB-T/DTPPSe-2F器件仍可实现14.13%的高效率,这是目前文献报道的空气氛围制备有机太阳能电池的最高效率之一.实验结果表明,P-ZnO作为电子传输层在构建高性能和空气稳定的有机太阳能电池方面具有巨大的应用潜力. 相似文献

Microbial cellulose (MC) membranes produced by Acetobacter xylinum NUST4.1,were used as flexible substrates for the fabrication of transparent indium tin oxide (ITO) electrodes.Transparent and conductive ITO thin films were deposited on MC membrane at room temperature using radio frequency (RF) magnetron sputtering.The optimum ITO deposition conditions were achieved by examining crystalline structure,surface morphology and op-toelectrical characteristics with X-ray diffraction (XRD),scanning electron microscopy (SEM),atomic force mi-croscopy (AFM),and UV spectroscopy.The sheet resistance of the samples was measured with a four-point probe and the resistivity of the film was calculated.The results reveal that the preferred orientation of the deposited ITO crystals is strongly dependent upon with oxygen content (O2/Ar,volume ratio) in the sputtering chamber.And the ITO crystalline structure directly determines the conductivity of ITO-deposited films.High conductive [sheet resis-tance ~120 Ω·square-1 (Ω·sq-1)] and transparent (above 76%) ITO thin films (240 nm thick) were obtained with a moderate sputtering power (about 60 W) and with an oxygen flow rate of 0.25 ml·min-1 (sccm) during the deposi-tion.These results show that the ITO-MC electrodes can find their potential application in optoelectrical devices. 相似文献
