These panels are billed as transparent to visible light, absorbing dominantly UV and IR radiation for their power generation. Based on that, I see no reason why you wouldn't want to build your greenhouse out of transparent solar cells. If you live in the right area, you might be able to power an electric pump off of the electricity to water your plants!
