研究目的
Investigating the performance of luminescent solar concentrators (LSCs) based on bi-component melt-spun polymer optical fibers for enhancing solar cell power production.
研究成果
The study demonstrated that COP is the best-suited host material for LR305 in terms of luminescent properties. The melt-spun bi-component fiber LSCs showed potential for enhancing the illumination-angle dependency of commercial PV solar panels, with optical conversion efficiencies between 2% and 15%. The high industrialization potential and overall performance suggest that such fibers could find applications in future photovoltaic systems.
研究不足
The study focuses on the performance of LSCs in absence of atmospheric effects, which may not fully represent real-world conditions. Additionally, the scalability and long-term stability of the melt-spun fibers in outdoor applications were not addressed.
1：Experimental Design and Method Selection:
The study involved the preparation of dye-doped polymer plates and melt-spun bi-component fibers. Molecular dynamics and Monte Carlo ray tracing simulations were used to link molecular properties to the plate geometry and results were validated experimentally.
2：Sample Selection and Data Sources:
Three thermoplastic polymers (COP, PMMA, PC) were evaluated as host materials for the luminescent dye LR305. The optical properties of these materials were measured using UV-Vis spectrophotometry and spectrofluorometry.
