Barrier of Light

Bottom line: The whole world says perovskites are a dead end. He didn't refute - he just locked himself in a leaky workshop, used a second-hand piece of equipment, and tried again and again until physics gave him an answer. In the late autumn of 200X, Chen Ming, a postdoctoral fellow at Tsinghua University, quit his job and lived alone in an abandoned workshop by the Suzhou River, using a second-hand glove box to develop perovskite batteries. At that time, the world was trapped in the contradiction between efficiency and stability, and many academic circles gave up. He was determined to develop a complete set of processes by himself, with no funding or team. Five of his classmates were recalled by him: Shen Qingye from MIT, Zhao Ming from Longi, Lin Xiaohe from the Chinese Academy of Sciences, investment manager Lu Zhixing, and veteran engineer Fang Zhiyuan. They each gave up their comfort and gathered in a shabby room. The efficiency of the first film was only 4.7%. Chen Ming locked it in the safe and engraved it as a note. Twenty years later, the workshop has become the origin of global technology. The 4.7% Film is placed side by side in the same cabinet as the fourth-generation "Pu Calcium". The color has changed, but the direction has not changed.
