The growth in distribution applications defines a new era for photovoltaics. Envisioned to be deployed widely in, for example, smart cities and Internet of Things, "self-powered" distributed applications will be required to harvest energy from surrounding energy sources. Thin film photovoltaics devices fabricated from the kesterite absorber Cu2ZnSn(SxSe1-x)4 (CZTSSe) combine high efficiency, low-cost and non-toxic materials, providing an attractive energy harvesting solution for the vast number of distributed applications in healthcare, transportation, construction, aerospace and consumer devices. Kesterite solar cells have the added benefit of solution-based fabrication via nanoparticle inks (Y. Qu, et al,. Prog. Photovolt. 2016) which is compatible with high volume and high value manufacturing.The ability to manufacture high efficiency CZTSSe thin film solar cells depends on achieving sufficiently high open circuit voltage. In this project, we aim to fabricate high performance CZTSSe solar cells by engineering the interface at the back contact.

配电应用的增长定义了光伏发电的新时代。设想在智能城市和物联网等领域广泛部署，“自供电”分布式应用将需要从周围能源中获取能量。由锌黄锡矿吸收剂 Cu2ZnSn(SxSe1-x)4 (CZTSSe) 制成的薄膜光伏器件结合了高效、低成本和无毒的材料，为医疗保健、交通、建筑、航空航天和消费设备中的大量分布式应用提供了有吸引力的能量收集解决方案。 Kesterite 太阳能电池具有通过纳米颗粒墨水进行基于溶液的制造的额外优势（Y. Qu 等人，Prog. Photovolt. 2016），可实现大批量和高价值制造。制造高效率 CZTSSe 薄膜太阳能电池的能力取决于实现足够高的开路电压。在这个项目中，我们的目标是通过设计背接触处的界面来制造高性能 CZTSSe 太阳能电池。
