研究了退火温度对Se0.70Ge0.15Sb0.15薄膜的影响.通过热蒸发技术,在300K温度下将大块无定形Se0.70Ge0.15Sb0.1s沉积在石英和玻璃衬底上.研究发现,未经过退火处理的薄膜结构和在300K,1.33×10-5Pa下退火1小时后的薄膜结构都是无定形结构,而在同样气压470K温度下退火1小时的薄膜有结晶现象.通过在300 2 500nm范围内垂直入射光方向上透射率和反射率的测试,研究了薄膜的一些光学参数,如消光系数(k),折射系数(n)和吸收系数(a).研究发现,n和k同热处理温度有关.通过光学数据的分析,得到了不同条件下薄膜的间接带隙宽度(Enong),未经过热处理薄膜的Enong是1.715±0.021eV,300K下退火薄膜的Enong是1.643±0.021eV,470K下退火的Enong是1.527±0.021eV.退火温度降低了带隙宽度Enong,但增加了带尾eo这种效应可以根据Mott和Davis提出的多晶体系中态密度来解释.

Kelvin probe force microscopy(KPFM) could identify the local work function of surface at nanoscale with high-resolution on the basis of simultaneous visualization of surface topography, which provides a unique route to in-situ study of the surface information like the composition and electronic states. Currently, as a non-destructive detection protocol, KPFM demonstrates the unique potential to probe the basic nature of perovskite materials that is extremely sensitive to water, oxygen and electron beam irradiation. This paper systematically introduces the fundamentals and working mode of KPFM, and elaborates the promising applications in perovskite solar cells for energy band structures and carrier transport dynamics, trap states, crystal phases, as well as ion migration explorations. The comprehensive understanding of such potential detection engineering may provide novel and effective approaches for unraveling the unique properties of perovskite solar cells.

The past few years have witnessed the extraordinarily rapid development of a class of photovoltaic devices based on organometal halide perovskites. Nevertheless, so far such new-fangled materials still contain performance-limiting defects leading to a bad performance. Herein, we introduce a novel NHPbI-based intermediate phase in crystallization growth process. To control the nucleation and crystal growth process, NHI additive is used to prepare perovskite films of high crystalline quality. A uniform and smooth perovskite film with reduced density of defects and long photoluminescence lifetime is obtained. The maximum power conversion efficiency of perovskite solar cells(PSCs) fabricated by this highly efficient film is up to 17%. The discovery of the innovative intermediate phase is probable to open a new sight to control crystallization of perovskite film and improve performance of PSCs.

本研究主要研究定常三维层流纳米流体在驻点区域的自由对流问题,利用相似性分析对问题的控制方程如质量守恒方程,动量守恒方程,能量守恒方程以及纳米粒子质量守恒方程进行简化。利用同伦-有限差分方法对问题进行求解,该方法继承了同伦分析方法求解强非线性问题的优势,又能大幅提高计算效率。并就相关参数对该纳米流动现象的物理特征包括速度剖面,温度剖面,纳米颗粒浓度分布的影响进行了详细讨论。对工程界较感兴趣的摩擦阻力系数、Nusselt数等物理参数进行计算和讨论。
