本文介绍了与多结太阳能电池辐照度不均匀性有关的效率损失机制，以及用于研究它们的不同测量技术。为了展示所提出的技术的能力，评估了三种不同的聚光器（由丙烯酸菲涅耳透镜，不同的soe和晶格匹配的多结单元组成）。在设计聚光器时，通过采用这些技术可以回答一些关键问题，例如，电池可以承受的非均匀性程度，串联电阻的影响有多严重，或者哪种非均匀性（空间或光谱）会导致更多的损耗。
This paper presents the mechanisms of efficiency losses that have to do with the non-uniformity of the irradiance over the multi-junction solar cells and different measurement techniques used to investigate them. To show the capabilities of the presented techniques, three different concentrators (that consist of an acrylic Fresnel lens, different SOEs and a lattice matched multi-junction cell) are evaluated. By employing these techniques is possible to answer some critical questions when designing concentrators as for example which degree of non-uniformity the cell can withstand, how critical the influence of series resistance is, or what kind of non-uniformity (spatial or spectral) causes more losses.
