Abstract

While waveguide-based light concentrators offer significant advantages, their application has not been considered an interesting option for assisting multijunction or other two-terminal tandem solar cells. In this study, we present a simple yet effective approach to enhancing the output power of transfer-printed multijunction InGaP/GaAs solar cells. By utilizing a simply combinable waveguide concentrator featuring a coplanar waveguide with BaSO4 Mie scattering elements, we enable the simultaneous absorption of directly illuminated solar flux and indirectly waveguided flux. The deployment of cells is optimized for front-surface photon collection in monofacial cells. Through systematic comparisons across various waveguide parameters, supported by both experimental and theoretical quantifications, we demonstrate a remarkable improvement in the maximum output power of a 26%-efficient cell, achieving an enhancement of ~93% with the integration of the optimal scattering waveguide. Additionally, a series of supplementary tests are conducted to explore the effective waveguide size, validate enhancements in arrayed cell module performance, and assess the drawbacks associated with rear illumination. These findings provide a comprehensive understanding of our proposed approach towards advancing multi-junction photovoltaics.

通过容纳可附加散射波导实现单片多结 III-V 光电功率倍增的合理策略。

虽然基于波导的聚光器具有显著优势，但其应用尚未被视为辅助多结或其他双端串联太阳能电池的有趣选择。在本研究中，我们提出了一种简单而有效的方法来提高转移印刷多结 InGaP/GaAs 太阳能电池的输出功率。通过利用一个简单可组合的波导聚光器，即带有 BaSO4 Mie 散射元件的共面波导，我们实现了同时吸收直接照射的太阳光通量和间接波导光通量。我们对电池的部署进行了优化，以便在单面电池中收集前表面光子。在实验和理论量化的支持下，通过对各种波导参数进行系统比较，我们证明 26% 效率电池的最大输出功率有了显著提高，在集成了最佳散射波导后提高了约 93%。此外，我们还进行了一系列补充测试，以探索有效波导尺寸，验证阵列电池模块性能的提升，并评估与后部照明相关的缺点。这些研究结果使人们对我们提出的推进多结光伏技术的方法有了全面的了解。
