关于机械化学生产的钙钛矿
On Perovskites Produced by Mechanochemistry
毫无疑问,光伏电池的未来将由钙钛矿族材料决定。波兰的化学家们研发了一种改进型钙钛矿,该晶体结构中含有较大的有机离子,即胍盐阳离子。实验室测试表明,由新型钙钛矿制备的光伏电池效率高于使用原始形式制备的电池。
There is no doubt: the immediate future of photovoltaics will be decided by materials from the perovskite group. An improved version of a perovskite, containing in the crystal structure a relatively large organic ion, a guanidinium cation, has been developed by chemists from Poland. Laboratory tests have shown that photovoltaic cells made of the new perovskite work more efficiently than the cells prepared using its original form.
Perovskites, substances that perfectly absord light, are the future of solar energy.
The opportunity for their rapid dissemination has just increased thanks to a cheap and environmentally safe method of production of these materials, developed by chemists from Warsaw, Poland. Rather than in solutions at ahigh temperature, perovskites can now be synthesized by solid-state mechanochemical processes: by grinding powsers.
