本文针对河北省南部电网变电站金属材料的腐蚀情况,分析了金属材料大气腐蚀的成因、大气腐蚀污染物的来源及解决方案,提出变电站选址应远离腐蚀性气体的释放源和江、河、湖泊、海边等潮湿地区,应选择空气流动好的区域,避免在沼泽洼地建站。针对大气中的腐蚀性气体的成分,选择合理的金属材料,达到防腐效果。针对不同部件的位置采取合适的防腐工艺进行防腐处理,在保证变电站生产要求的基础上,解决材料的防腐工作。

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
