PFN-Br interfacial layer entrenched in OPV devices gives overall enhanced open-circuit voltage, short-circuit current density and fill factor thus improving device performance. PEDOT: PSS is an electro-conductive polymer solution that has been extensively utilized in solar cell devices as a hole transport layer (HTL) due to its strong hole affinity, good thermal and mechanical stability, high work function, and high transparency in the visible range. The structure of the organic solar cell is ITO/PEDOT: PSS/BTP-4F: PBDB-T-2F/PFN-Br/Ag. Firstly, the active layer thickness was optimized to 100 nm;after that, the active-layer thickness was varied up to 900 nm. The results of these simulations demonstrated that the active layer thickness improves efficiency significantly up to 500 nm, then it decreased with increasing the thickness of the active layer from 600 nm, also notice that the short circuit current and the fill factor decrease with increasing the active layer from 600 nm, while the open voltage circuit increased with increasing the thickness of the active layer. The optimum thickness is 500 nm.展开更多
文摘目的 筛选卵巢癌预后不良的分子生物学标志。方法 从GEO数据库获得卵巢癌GSE14001、GSE14407数据集,用在线分析工具GEO2R、Venn筛选得到卵巢癌和正常卵巢组织差异表达基因(DEGs),对DEGs进行富集分析,构建蛋白互作网络(PPI),以及构建网络模块得到关键基因,利用Kaplan Meier plotter网站分析关键基因与卵巢癌患者总生存期之间关系,应用GEPIA数据库分析DEGs在卵巢和卵巢癌组织中表达,应用The Human Protein Atlas数据库获取筛选基因的免疫组化结果,对比它们在卵巢和卵巢癌组织间的表达差异。结果 得到211个DEGs,92个上调和119个下调。差异基因生物学过程主要涉及侧枝发芽的正向调控、乏氧反应、间充质-上皮细胞信号传导;细胞组分主要集中在质膜顶、细胞表面、细胞外外泌体等部位;分子功能主要涉及丝氨酸型内肽酶活性、金属内肽酶活性、受体活性等;信号通路富集于白细胞跨内皮细胞迁移、细胞黏附通路、癌症通路等信号通路。得到35个候选基因,其中14个基因高表达、8个基因低表达与患者总生存期相关(P<0.05)。其中ATP6V1F、GINS1、GINS4基因在卵巢癌组织中在RNA水平和蛋白质水平表达均高于正常组织(P<0.05)。GNB3在卵巢癌组织中RNA水平表达低于正常组织,而在蛋白质水平恰好相反(P<0.05)。结论 ATP6V1F、GINS1、GINS4有可能是卵巢癌预后不良的新分子标志物。
