太阳能电池能把光能转换成电能。目前所使用太阳能电池有多种设计类型，主要的挑战是如何更广泛的使用这些技术，这需要提高设备的性能，以及降低成本。
下面的例子展示了如何结合EDS、EBSD和EBIC来表征Cu(In,Ga)Se2吸收层。通常认为晶界对光电转化性能有不利影响，但该例子展示了尽管在材料中有大量的晶界，这些太阳能电池的光电转化性能仍然很高。通过EBSD和EBIC数据可以证明不仅仅是密度的问题，晶界的类型也很重要。

该设计基于多层氧化层结构，单个氧化层厚对器件光电转化性能有显著影响。这意味着测量和控制层厚对于确保理想性能至关重要。这个例子展示了如何使用 AZtec LayerProbe 对多层结构的厚度和组成进行无损分析。

Electron Beam Induced Current is a wellestablished analysis method of electrical activity in the SEM (and occasionally in the STEM). It provides a unique correlation of electrical and structural properties with very spatial resolution.
Photovoltaic (PV) cells are an attractive option for generating carbon renewable energy but traditional designs often include undesirable toxic compounds and must be manufactured under special conditions. The all-oxide approach to photovoltaic cells is thus very attractive...
