Although low-temperature,solution-processed zinc oxide (ZnO) has been widely adopted as the electron collection layer (ECL) in perovskite solar cells (PSCs) because of its simple synthesis and excellent electrical properties such as high charge mobility,the thermal stability of the perovskite films deposited atop ZnO layer remains as a major issue.Herein,we addressed this problem by employing aluminum-doped zinc oxide (AZO) as the ECL and obtained extraordinarily thermally stable perovskite layers.

经过六年的努力,钙钛矿太阳能电池的光电转换效率从3.8％提高到20％多,并且由于其制作成本相对较低,工艺易操作等优点引起了科学界广泛的关注.在钙钛矿太阳能电池光阳极材料研究中,人们除了研究制备不同形貌的TiO2 如:纳米管、纳米棒等来提高电池的性能外,还有对TiO2 基质进行掺杂处理.掺杂元素一般有金属掺杂和非金属掺杂两类,非金属元素掺杂的出发点是基于TiO2 基材中存在大量的氧缺陷浓度,会降低电

Herein,we reported the nonlinear optical response of triiodide (CH3NH3PbI3) and mixed halide (CH3NH3PbI3-xClx) perovskite thin films.The results demonstrated that they have large nonlinear refractive
We developed a facile,but efficient,layer-by-layer approach to uniform CH3NH3PbI3-xClx perovskite flat films for high-performance perovskite solar cells (Figure 1,left).1 Briefly,a thin layer of Lead
Formamidinium lead iodide (FAPbI3) is a more promising absorber material than methylammonium lead iodide (MAPbI3) for PSCs because of its smaller bandgap(1.48 ev) and better thermal stability.In previ
钙钛矿太阳能电池中电子传输层的材料一直是以TiO2 为主,由于需要450℃的高温烧结而制约了其在柔性钙钛矿电子器件上的应用.因此寻找其它材料替代TiO2 作为空穴阻挡层一直是近年来冉冉升起的钙钛矿电池的一个研究方向.与TiO2 相比,SnO2 由于其相对较高的电子迁移率和本身较宽的光学带隙在最近引起了广泛关注.然而其较浅的导带能级和薄膜本身存在的一些缺陷制约了其进一步的应用.本文通过一种简单的Ti
