Advances in transparent solar cells mean that soon we might be able to install them into windows and greenhouses. But in the latter case, would they deprive plants of vital sunlight? To find out, researchers at North Carolina State University grew lettuce under various wavelengths of light, and found that the plants did just fine.

Organic solar cells are emerging as a viable system for renewable energy, thanks to a number of advantages. They can be more flexible than other technologies, be made transparent or semi-transparent, and the wavelengths of light they harvest can be adjusted.

In theory, that could make them perfect for embedding into greenhouse roofs. There, these organic solar cells could capture certain wavelengths of light while still allowing some of it to pass through to the plants below. In a previous study, the NC State team investigated how much energy this kind of setup could produce, and found that it could be enough to make greenhouses energy neutral.

But of course there’s one big piece of that puzzle missing – nobody asked the plants how it affected them. So that was the focus of the new work.
