Abstract
A photovoltaic greenhouse includes a house structure having upstanding walls and a roof thereover to enclose a greenhouse space therein, and at least one thin-film solar cell module mounted on the roof for converting solar energy within a pre-selected light band of sunlight into electricity, wherein light not absorbed by the thin-film solar cell module passes through and enters the greenhouse space, which can be utilized by plants or crops for photosynthesis. The thin-film solar cell module has high transmittance of light in the wavelength intervals, for example, 400-450 nm and 640-700 nm, required by the cultured plants or crops inside the greenhouse space for photosynthesis.
Claims20
A photovoltaic greenhouse for culturing plants or crops therein, comprising:
- a main greenhouse frame structure comprising a plurality of upstanding walls and a roof supported by said upstanding walls;
- and
- at least one transmissive thin-film solar cell module mounted on said roof for partially absorbing a pre-selected light band of sunlight into electricity and allowing a transmitted sunlight, excluded from the pre-selected light band of partially absorbed sunlight, to pass through the thin-film solar cell module to enter the greenhouse for benefiting growth of the plants or crops.
A thin-film solar cell module which selectively converts a pre-selected light band of sunlight into electricity, characterized in that:
- a filter is disposed under said thin-film solar cell module to make said thin-film solar cell module become light-band selective and allowing a transmitted sunlight, excluded from the pre-selected light band of partially absorbed sunlight to pass therethrough.
