They found that red wavelengths are more efficient for growing plants, while the blue part of the spectrum is better for producing solar energy.Solar panels that only allow red wavelengths of light to pass through could enable farmers to grow food more productively while generating power at the same time.Majdi Abou Najm, an associate professor at University of California, Davis' department of land, air and water resources, told that by splitting the light spectrum, crops can get the same amount of carbon dioxide with less water while shielding them from heat.For this approach to work in practice, though, manufacturers would need to develop translucent solar panels that capture blue light and allow red light to pass through.Matteo Camporese, an associate professor at the University of Padova in Italy and lead author of on the topic, suggested that translucent, carbon-based organic solar cells could work."
