Unlike traditional LSCs, HLSCs focus on converting energy from one part of the solar spectrum (typically green) to a specific range (usually red) and aim for the converted photons to exit the device from the bottom surface rather than the edge surfaces. Thus, beyond spectral conversion, HLSCs are especially notable for their light extraction capabilities. Efficient spectral conversion and outcoupling efficiency are achieved by optimizing luminescent materials and introducing light extraction techniques. In this study, we start by examining the specific requirements of horticulture to clarify the motivation for using HLSCs. We re-evaluate and propose new optical metrics tailored to HLSCs. Additionally, we analyse potential loss channels for direct red emission and converted red emission. Utilizing Monte Carlo ray tracing method and experimental data, we further explore the factors influencing these loss channels. The key evaluation metrics for HLSC and LSC are compared to highlight the distinctions between the two, emphasizing the innovative features of the HLSC device. Our work provides a fundamental discussion on HLSCs and offers design guidelines for future HLSC research. date: 2025-12 date_type: published publisher: Institute of Electrical and Electronics Engineers (IEEE) official_url: https://doi.org/10.1109/jstqe.2025.3540601 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2366050 doi: 10.1109/JSTQE.2025.3540601 lyricists_name: Papakonstantinou, Ioannis lyricists_name: Xu, Zhijie lyricists_id: IPAPA54 lyricists_id: ZXUDX15 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public publication: IEEE Journal of Selected Topics in Quantum Electronics volume: 31 number: 6 article_number: 6000212 citation: Xu, Z; Yu, Y; Papakonstantinou, I; (2025) Performance Metrics and Loss Mechanisms in Horticulture Luminescent Solar Concentrators.
