The electron transport layer （ETL） plays an important role in planar heterojunction perovskite solar cell （PSCs）, by affecting the light-harvesting, electron injection and transportation processes, and especially the crystal- lization of perovskite absorber. In this work, we utilized a commercial TKD-TiO2 nanoparticle with a small diameter of 6 nm for the first time to prepare a compact ETL by spin coating. The packing of small-size particles endowed TKD-TiO2 ETL an appropriate surface-wettability, which is beneficial to the crystallization of perovskite deposited via solution-processed method. The uniform and high-transmittance TKD-TiO2 films were successfully incorporated into PSCs as ETLs. Further careful optimization of ETL thickness gave birth to a highest power conversion efficiency of 11.0%, which was much higher than that of PSC using an ETL with the same thickness made by spray pyrolysis. This TKD-TiO2 provided a universal solar material suitable for the further large-scale production of PSCs. The excellent morphology and the convenient preparation method of TKD-TiO2 film gave it an extensive application in photovoltaic devices.

针对非均质移动颗粒床的换热过程,建立了其渗流换热的数学模型,提出了COADI-GS算法,采用此算法对移动颗粒床的气固换热过程进行流热耦合数值模拟。通过对均质与非均质这两种不同移动颗粒床换热模型的仿真结果进行比较,发现两者的床内温度分布有较大差异,非均质移动颗粒床模型能更为准确地描述床层内的渗流换热过程。计算结果表明,供风压力的增加虽有利于熟料颗粒的冷却,但会降低回收风的温度;颗粒温度随床层移动速度的增加而升高,近似为线性关系。

针对初始聚类中心不合理的选择会导致K-means算法的聚类结果局部最优,且降低聚类算法收敛速度的问题,提出一种基于近邻传播算法和最大最小距离算法联合计算初始聚类中心的算法(APMMD)。该算法通过近邻传播算法从整个样本集中获得Kap(Kap>k)个具有代表性的候选中心点,再利用最大最小距离算法从Kap个候选中心点中选择k个初始聚类中心。在多个UCI数据集上实验,结果表明APMMD算法获得初始聚类中心应用于K-means聚类,迭代次数明显降低,聚类结果稳定且具有较高准确率。
