Recently, the Facility Plant Environmental Engineering Innovation Team of the Institute of Agricultural Environment and Sustainable Development, Chinese Academy of Agricultural Sciences has made new progress in the research on multi-spectral efficient conversion of solar energy in plant factories. This study proposes a plant spectrum complementary method for solar energy frequency-conducting light-photothermal synergistic conversion, and establishes a theoretical model of light-matter interaction at multi-wavelength scales, which is of great significance for further reducing the energy consumption of plant factories.
The application of solar light conduction lighting technology to plant factories can greatly reduce the energy consumption of light sources in plant factories. However, only part of the visible light in the sunlight can directly participate in the photosynthetic reaction process of crops, and the remaining spectrum will cause the ambient temperature in the plant factory to rise and increase the cooling energy consumption of the air conditioner.
The research team proposed a spectrum and light intensity synergistic optimization system for plant factories. The system not only conducts photosynthetic spectrum for plants, but also converts non-photosynthetically active radiation spectrum into thermal energy for storage. At the same time, in order to better match the photovoltaic needs of plant factories, this research will be further combined with photovoltaic, thermoelectric power generation and other technologies to open up a new way for the realization of low energy consumption and sustainable plant factory development.
