Enabling technology unlocking full potential of high bandgap chalcopyrite

该项目旨在解决高带隙黄铜矿捕光材料的根本挑战，以充分释放其作为光伏串联电池顶部电池和光电化学应用的光电阴极的潜力。这将通过动态优化其在光伏太阳能电池器件中的性能来实现，方法是了解其缺陷来源，实现缺陷控制技术，并通过系统的宏微观表征与3D器件模拟相结合的微观载流子损失机理分析。该项目的完成将通过高效、稳定、符合RoHS标准的薄黄铜矿设备来加强下一代串联电池和光电化学技术。

This project is aimed at solving the fundamental challenges of high bandgap chalcopyrite light-harvesting material to unlock its full potential as the top cell for photovoltaic tandem cell and the photocathode for photoelectrochemical applications. This will be realised by dynamic optimisation of its performance in photovoltaic solar cell device through understanding of its defects origins, enabling defects controlling technologies, and microscopic carrier loss mechanism analysis via systematic macro-to-micro characterisations combined with 3D device simulation. The project completion will reinforce the next-generation tandem cell and photoelectrochemical technologies with the efficient, stable, RoHS-compliant and thin chalcopyrite devices.
