| Abstract |
Greenhouses are mostly made of acrylic or glass materials, so that sunlight can penetrate into the greenhouse for plants to absorb. At present, greenhouse planting technology has been widely used in the cultivation of plants. If further consideration is given to the government′s 2050 net-zero carbon emissions and the development of green energy, the integration of solar cells and greenhouse facilities with novel optoelectronic materials can not only provide electricity for smart agricultural facilities but also achieve the goal of zero carbon emission or even negative carbon emission. However, while solar power generation, it must also let the light needed by plants pass through; thus, semitransparent solar cells come out as a good solution. The chlorophyll of plants mainly uses blue light (400nm-500nm) and red light (600nm-700nm) for photosynthesis, and the application of far-infrared light (700nm-850nm) makes plants produce shade avoidance response (Shade avoidance response), thereby promoting plant growth. In this study, we will investigate the semitransparent solar cells with three novel optoelectronic materials (including organic conductive polymers or small molecules, perovskites, dyes), and integrate these solar cells to the greenhouse to provide the electricity required for the greenhouse. Because the light absorption range of these novel optoelectronic materials can be tuned, the semitransparent solar cells can regulate the sunlight that penetrates into the greenhouse to achieve power generation and precise control of plant growth rate and immunity. |
