Ultra High Efficiency Solar Cells Using SiGeSn (HESCUS)

该项目的目的是满足对效率更高的太阳能电池的需求，用于地面发电和空间发电。该项目打算扩展已经处于领先地位的技术，并添加一种新型半导体材料（SiGeSn），以更好地使该设备的子电池的吸收波长与太阳光谱相匹配。通过这样做，预计这种装置的转换效率可以从4J多太阳地面电池的~39%增加到接近50%，从1太阳4J AM0空间太阳能电池的~28%增加到~35%，大大提高了两个应用领域的单位面积发电量。

The project aims to address the need for ever higher efficency solar cells for terrestrial energy generation and also for space power applications. The Project intends to extend already leading edge technology and add a novel semiconductor material (SiGeSn) to better enable matching of the absorption wavelengths of the sub-cells of the device to the solar spectrum. By doing this it is anticipated that the conversion efficency of such a device can be increased from ~39% to close to 50% for a 4J multi-sun terrestrial cell, and from ~28% to ~35% for a 1-sun 4J AM0 space solar cell, greatly enhancing power generated per unit area for both application areas.
