Thin-film photovoltaic panel greenhouse

Are organic photovoltaics a smart greenhouse?

Hence, a smart greenhouse with semi-transparent organic photovoltaics (OPVs) integrated into the power-generating roof is highly desirable for modern agriculture 2, 3. Due to the unique band structure of organic materials, OPVs are able to selectively absorb light with a desired wavelength 4, 5, 6.

Can photonic films be used as greenhouse envelopes?

The photonic films can, as we demonstrate experimentally, serve as greenhouse envelopes to provide more effective photosynthetic light than that of direct sunlight, opening the door for ‘red-coloured’ greenhouses with substantially augmented yields. Not every spectral component of sunlight contributes equally to photosynthesis 6.

Are semi-transparent organic photovoltaics feasible?

Semi-transparent organic photovoltaics (OPVs) are an emerging solar-energy-harvesting technology with promising applications, such as rooftop energy supplies for environmentally friendly greenhouses. However, the poor operational stability of OPVs poses challenges to their feasibility as incessantly serving facilities.

Can spectral-shifting microphotonic thin film improve photosynthesis and light capture?

Provided by the Springer Nature SharedIt content-sharing initiative Improving photosynthesis and light capture increases crop yield and paves a sustainable way to meet the growing global food demand. Here we introduce a spectral-shifting microphotonic thin film as a greenhouse envelope that can be scalably manufactured for augmented photosynthesis.

Do semi-transparent OPV-integrated greenhouses improve plant growth?

The integration of the resulting semi-transparent OPVs in the power-generating roof shows that plant growth in the semi-transparent OPV-integrated greenhouse is improved relative to that in the traditional glass-roof greenhouse with a higher survival rate.
