This review points out the current need for further research on tandem solar cells as the commercial single-junction solar cell technologies report close to their maximum performance limit. First, the conceptual insight and the desired interconnection schemes for tandem solar cells are briefly presented. Then, a comprehensive discussion on the structural, optical, and electronic properties of CuGaSe₂, evaluating its use as a top cell absorber material, is presented. Furthermore, the current status and the critical analysis of CuGaSe₂ solar cells, which finds that the adapted conventional device architecture possesses severe limitations, are presented. Based on the drawbacks of the existing materials in use, new materials to fabricate CuGaSe₂ solar cells are proposed. Also, tandem configurations with newly proposed CuGaSe₂ solar cell architecture by choosing Si photovoltaics as bottom cells are devised. In the end, further challenges in the devised tandem configurations with a focus on their band alignments are elucidated.

CuGaSe2/Si串联太阳能电池制造的综合视角

这篇综述指出目前需要对串联太阳能电池进行进一步研究，因为商业单结太阳能电池技术报告接近其最大性能极限。首先，简要介绍串联太阳能电池的概念见解和所需的互连方案。然后，全面讨论了 CuGaSe ₂的结构、光学和电子特性，评估其作为顶部电池吸收材料的用途。此外，还介绍了 CuGaSe ₂太阳能电池的现状和批判性分析，发现适应的传统器件架构具有严重的局限性。基于现有材料在使用中的缺点，新材料制造CuGaSe ₂提出了太阳能电池。此外，通过选择硅光伏作为底部电池，设计了与新提出的 CuGaSe ₂太阳能电池架构的串联配置。最后，阐明了设计的串联配置中的进一步挑战，重点是它们的带对齐。
