COating for SMArt GREENhouses

Project description

New greenhouse coating to enhance photosynthesis

It is the pigment called chlorophyll in green plants that makes them green. It absorbs blue and red light (the long and short wavelengths of the visible light spectrum), causing the plant to look green. This means the solar spectrum is not optimised for energy conversion. For instance, the use of standard fluorescent pigments in a coating at the top of a greenhouse means that half of the converted sunlight is emitted back to space – lowering the conversion efficiency. The EU-funded COSMAGREEN project will design a greenhouse coating that can actually increase the effective light inside in order to enhance the process of photosynthesis. Specifically, it will use coatings that have nano-antenna phosphor pairs that will help to reduce the back-emitted light.
