Definitions
- a luminescent solar energy collection device comprising: a transparent substrate; at least one solar cell disposed on a partial area of one side of the transparent substrate; and a photoluminescent layer disposed on the transparent substrate The side of the substrate is provided with the solar cell and covers the solar cell, wherein the photoluminescent layer is in contact with at least part of the solar cell to fix the solar cell on the transparent substrate.
- the thickness of the transparent adhesive layer is below 200 microns.
- the photoluminescent layer and the solar cells are at least partially in contact to secure the solar cells on the transparent substrate, enabling the use of adhesive layers to be reduced or even avoided entirely Therefore, the thickness of the entire product can be reduced and the light transmittance can be improved, and the product manufacturing process can be simplified, and the material and process costs can be reduced.
- FIG. 2 is only a schematic cross-sectional view according to some embodiments of the present disclosure.
- a luminescent solar energy collection device may be provided with fewer or more solar cells at the location where the cross-sectional view is taken.
- the number of solar cells of the light-emitting solar energy collecting device is not particularly limited, and can be appropriately set according to the entire plane area of the light-emitting solar energy collecting device and the spacing requirements between adjacent solar cells.
- the material of the transparent substrate 100 may be any suitable transparent substrate such as a glass substrate, a polymethyl methacrylate (PMMA) substrate, a polycarbonate substrate, and the like.
- Transparent here means that light is not absorbed when it propagates, but this is only an ideal state, and light may be absorbed in a small amount.
- the transmittance of the transparent substrate there is no particular requirement for the transmittance of the transparent substrate.
- the higher the transmittance the better the utilization efficiency of light.
- the visible light transmittance of the transparent substrate may be above 80%.
- the transparent substrate and the photoluminescent layer have approximately the same refractive index, and when the two are stacked together, they also function as optical waveguides, allowing light to propagate through total reflection. Therefore, after the light enters the transparent substrate and the photoluminescent layer, it can be totally reflected and propagated inside the transparent substrate and the photoluminescent layer. During the process of total reflection and propagation, the absorption rate of the light by the solar cell and the photoluminescent layer itself is further improved. . In order to better enable total reflection propagation in the photoluminescent layer, the sum of the thicknesses of the transparent substrate and the photoluminescent layer is, for example, greater than the thickness of the solar cell by more than 300 microns.
- the material of the adhesive layer 400 is not particularly limited, and it can be a curable transparent glue material.
- it can be the above-mentioned transparent glue for the base material of the photoluminescent layer.
- it can be optical glue OCR.
- the material of the tie layer may be the same as or different from the matrix material in the photoluminescent layer.
- the light-emitting solar energy collecting device can be applied to the field of agricultural technology.
- luminous solar energy collection devices can be applied to agricultural greenhouses.
- the light-emitting solar energy collecting device is used as a light-transmitting window of an agricultural greenhouse, thereby forming an efficient ecological photovoltaic agricultural greenhouse.
- the side of the transparent substrate can be directed to the outside, that is, the side facing the sun. This agricultural greenhouse does not occupy additional cultivated land, realizes the appreciation of the original land, combines ecological agriculture and green power generation, and maximizes the use of resources.
