Agrivoltaic systems offer a solution to the debate over using agricultural land for food production or energy conversion. Conventional silicon solar panels often shade plants excessively, impacting growth. Wavelength-selective photovoltaic (WSPV) technologies address this by allowing the transmission of beneficial wavelengths for photosynthesis while converting less useful ones into electricity. Wavelength selectivity can be achieved through various methods, such as by tuning photoactive layers, applying colored semi-transparent layers, utilizing mirrors and lenses, or designing spectrally selective luminophores. While evidence suggests that these technologies effectively share sunlight, many of them are yet to be fully implemented and evaluated. This review covers current WSPV technologies, discussing their classification, status, and future prospects. It also provides appropriate PV performance metrics for WSPV technologies in agricultural applications and advocates for standardized reporting practices in crop experiments conducted under WSPV systems, accompanied by practical suggestions. Solar cell efficiency limits under spectral sharing for crop production and the optimal band gap under varying levels of photosynthetically active radiation for crop growth are further examined as guidance for future development.

波长选择性太阳能光伏系统可增强农业光伏中阳光的光谱共享


农业光伏系统为有关利用农业土地进行粮食生产或能源转换的争论提供了解决方案。传统的硅太阳能电池板经常过度遮蔽植物，影响生长。波长选择性光伏（WSPV）技术通过允许传输对光合作用有益的波长，同时将不太有用的波长转化为电能来解决这个问题。波长选择性可以通过多种方法实现，例如通过调整光敏层、应用彩色半透明层、利用镜子和透镜或设计光谱选择性发光体。虽然有证据表明这些技术可以有效地共享阳光，但其中许多技术尚未得到充分实施和评估。本综述涵盖了当前的 WSPV 技术，讨论了它们的分类、现状和未来前景。它还为农业应用中的 WSPV 技术提供了适当的光伏性能指标，并倡导在 WSPV 系统下进行的作物实验中采用标准化报告实践，并附有实用建议。进一步研究作物生产光谱共享下的太阳能电池效率限制以及作物生长不同光合有效辐射水平下的最佳带隙，作为未来发展的指导。
