• 点评：硒化反应是决定铜锌锡硫硒薄膜品质的核心环节，若该过程中金属离子迁移的动力学失衡，会催生高浓度深能级的缺陷，最终造成显著的开路电压损失。该研究从材料生长机理层面，系统诠释了“离子迁移—缺陷—性能”的关系，并攻克了铜锌锡硫硒太阳能电池硒化阶段金属离子迁移难以调控的核心难题，为低成本、环保型薄膜太阳能电池的产业化发展提供了关键的技术支撑。（柯玉圆）
Smart ring maker Oura has acquired Doublepoint, a company that specializes in gesture recognition for wearables. The Finnish startup uses smartwatches and wristbands as examples of products that benefit from its technology, but Oura will clearly be looking to incorporate it into its rings, in theory allowing you to control your connected devices with hand movements.
