Brendan O’Connor, author and an associate professor of aerospace and mechanical engineering at NC State says that the plants do not use all of the wavelengths of light for photosynthesis. So the unused light can be used to make energy by creating greenhouse that can use the energy from the photosynthesis from the plants. He also talks about doing it certain ways. It was necessary to use the spectrum of light as it absorbed by the solar light. It is easy to use those unused wavelengths of light from plants. Though scientists were unaware about the energy used by the green house if it was using the organic solar cells which are selective of the wavelengths and are semi-transparent in nature.
To find out the answer of this question, a computational model was used to predict about the amount of energy that can be produced by the green house having organic cells of selective wavelengths and semi-transparent nature. It will be attached to its roof and monitored if the energy would be sufficient to offset the amount of energy the greenhouse required to operate effectively.
O’Connor states that major part of the energy that is used in greenhouses comes from heating and cooling so the model calculates the amount of energy produced by a greenhouse at various locations when we place the solar cells on its roof.
There is a trade-off between the power generated by solar cells and the light in the photosynthetic band that they allow to pass through which makes the modelling a complex structure.
Infrared light is reflected by the solar cells that are used for this analysis and they are mostly effective insulators hence it keeps the greenhouse cool in the summer and keeps warm in winter.
O’Connor says that the impact on the plants will be negligible even if the light energy is used by the green house on which the plants rely also the trade-off will make financial sense to growers.
