摘要: The spectral range of plant photosynthesis primarily lies within the visible light band (380-780 nm), while theintroduction of near-infrared light (780-2500 nm) imposes unnecessary thermal loads, $olar transmission illu.mination through visible light conduction is one of the most efficient approaches in solar building applications.To enhance solar energy utilization and mitigate adverse infrared effects on optical fibers and plant factories, thisstudy proposes an lntegrated $olar Transmission luminating and Photovoltaic (lTiPV) system based on com.posite phase change material cooling. A spectral splitter separates the solar spectrum: visible light supports cropgrowth, while near-infrared is directed to PV cells for power generation, Nanographite-paraffin composite phasechange materials are employed to cool the PV cells, Experimental results show pV cells operate steadily at43.5 'C, The system achieves average power generation and light transmission efficiencies of 9.5 % and 18.9 %.respectively, The levelized cost of energy (LCOE) is 0.055 USD/kWh, significantly lower than China's residentialelectricity price (0.084 USD/kWh), This study offers a novel strategy to improve solar transmission illuminationefficiency.
