纯硫化物CIGS太阳能电池是独立太阳能电池或串联配置的顶部电池的有趣候选者。为了了解这些器件的局限性并提高其功率转换效率，应采用针对组成、接口和工艺工程的综合方法。在这里，对后者进行了探讨。使用两步制造技术和一个变量在一个时间的方法，我们发现四个工艺因素影响的吸收体。虽然其中两个已经得到了以前文献的支持，但我们还发现了另外两个重要因素的新的统计证据。碱屏障扩散的影响也建立了统计学意义，并在各种加工条件下。此外，没有屏障的样品的吸收体粗糙度表明与器件的效率显著负线性相关。这一贡献可以帮助工程师进行更有效的工艺设计。
Pure sulfide CIGS solar cells are interesting candidates for standalone solar cells or top cells in a tandem configuration. To understand the limits and improve the power conversion efficiency of these devices, a comprehensive approach aimed at composition, interface, and process engineering should be employed. Here, the latter was explored. Using a two-step fabrication technique and one-variable-at-a-time methodology, we found the four processing factors affecting the absorber the most. While two were already backed by the previous literature, we found new and statistical evidence for two other important factors as well. The impact of alkali barrier diffusion was also established with statistical significance and under various processing conditions. Furthermore, the absorber roughness for samples without a barrier indicated a significant negative linear correlation with the devices’ efficiency. This contribution could aid engineers in more efficient process designs.
