日本提高钙钛矿太阳能电池转换率
日本 钙钛矿 太阳能电池 转换率
2017/12/5
据日本当地媒体报道，针对新一代太阳能电池“钙钛矿太阳电池”材料，东京大学先端科学技术研究中心的科研人员，在不使用铷等稀有金属的前提下，实现了20.5%的高转换效率及稳定发电。研究通过添加地球上较多存在的钾元素，实现了结晶构造的稳定性。研究组在进行长期耐久性试验同时，面向松下、东芝等企业的实用化进行评价与研讨。

俄罗斯研发出防水耐磨新技术
俄罗斯 防水耐磨新技术 合金材料
2017/11/21
攀荷弄其珠，荡漾不成圆。受荷叶不沾水的原理启发，并辅以化学处理新工艺，俄罗斯研究团队日前研发出一种提升铝镁合金材料防水耐磨性能的新技术。
荷叶表面遍布极微小的凸起和绒毛，落到荷叶上的雨水会被这种凹凸结构所排斥并快速流走，难以洇湿叶片。俄科学院物理化学与电化学研究所的科研团队依据这一防水机制并拓展利用，借助大量纳秒级激光脉冲“轰击”铝镁合金材料，使其表面产生与荷叶类似、凹凸深浅为纳米和微米尺度的特...

乌克兰 新型 非晶纳米 晶带材
2017/11/7
乌克兰国家科学院金属物理研究所发布消息称，其研究人员开发出一种铁基ХКБРС合金，可用于生产加热元件。这种合金的非晶化倾向高，它既是金属，也是金属玻璃。普通的无定形金属加热和转变为结晶状态时会受损，当温度（如大于200℃）升高时，变得非常脆弱，而用该合金制成的加热元件属于低温制品，不会受损。
