Abstract

Micro-concentrator solar cells offer an attractive way to further enhance the efficiency of planar-cell technologies while saving absorber material. Here, two laser-based bottom-up processes for the fabrication of regular arrays of CuInSe and Cu(In,Ga)Se microabsorber islands are presented, namely one approach based on nucleation and one based on laser-induced forward transfer. Additionally, a procedure for processing these microabsorbers to functioning micro solar cells connected in parallel is demonstrated. The resulting cells show up to 2.9% efficiency and a significant efficiency enhancement under concentrated illumination.

摘要

微聚光太阳能电池提供了一种颇具吸引力的方法，可在节省吸收体材料的同时进一步提高平面电池技术的效率。本文介绍了两种基于激光的自下而上的工艺，用于制造CuInSe和Cu(In,Ga)Se微吸收体岛的规则阵列，即一种基于成核的方法和一种基于激光诱导正向转移的方法。此外，还展示了一种将这些微吸收体加工成并联连接的功能性微太阳能电池的工艺。所得电池在聚光照明下的效率高达2.9%，且效率有显著提高。
