Lettuce farming can be sustainable and energy efficient

Lettuce farming can be sustainable and energy efficient: Under transparent solar cells Greenhouse farming of lettuce can be sustainable and energy efficient.

Semi-transparent organic solar cells (OSCs) can help green house growers reduce energy use, generate electricity and cultivate lettuce, this is according to a new study by a team of researchers at North Carolina State University.

Working with the biological photovoltaic cell company NextGen Nano, scientsts , believe OSCs provide a way for greenhouse farming without the large energy demands traditionally associated with it.

The research found that red lettuce can be grown in greehouses with OSCs that filter out the wavelengths of light used to generate solar power this was published in Cell Reports Physical Science.

It is possible that to use clear solar panels in greenhouses to cover their high electricity needs while not shrinking the crop yield.

“Greenhouses are used to grow plants because they drastically increase yield in non-native climates, while lowering water consumption and pesticide use compared to conventional farming.” said Doctor Carr Ho, Research Scientist at NextGen Nano.

“But greenhouse glazing has poor thermal insulation, so heating and ventilation systems need to be installed to help maintain optimal conditions. Along with supplemental lighting, this lights to large, unsustainable energy consumptions.”
