Researchers at the Mälardalen University in Sweden have provided an extensive review of all wavelength-selective PV systems for applications in agrivoltaics.

“Traditional opaque silicon panels often create excessive shading that limits light availability for most shade-intolerant crops. Yet, plants do not need the full spectrum of sunlight for growth but only the region where they are photosynthetically active. In some cases, a full spectrum may even hinder their development,” the research's lead author, Silvia Ma Lu, told pv magazine. “This opens the door for wavelength-selective solar photovoltaic (WSPV) technologies. WSPV systems are designed to transmit light at the wavelengths most beneficial for photosynthesis, while reflecting or absorbing less essential wavelengths to generate electricity.”
