Embodiment Construction

[0011] As shown in the figure, a monocrystalline silicon battery module with adjustable light transmittance includes at least a battery module backplane 1, a PVB film layer 2, a photosensitive intermediate film layer 3, and a PVB film layer 4 that are bonded to each other from bottom to top , Monocrystalline silicon cell combination layer 5, PVB film layer 6, and embossed glass layer 7.

[0012] The battery pack back plate 1 is a PE plate or 8 mm transparent glass with a thickness of 3 mm.

[0013] The thickness of the PVB film layers 2, 4, and 6 is 0.76 mm. Mainly play the role of bonding the upper and lower layers.

[0014] The photosensitive intermediate film layer 3 is a doped vanadium dioxide phase change smart material layer. It is a doped vanadium dioxide precursor prepared on the PVB film layer 2 by a liquid phase deposition method, and the V obtained after filtering, washing, drying, heating, and crystallization 1 - x M x O x (0 <X <0.06) Phase change smart material, the ...

Abstract

The invention discloses a light-transmittance-adjustable single crystal silicon cell assembl which is characterized by at least comprising a cell assembly backboard, a PVB (polyvinyl butyral) photoplate layer, a photosensitive middle film layer, a PVB photoplate layer, a single crystal silicon cell piece composite layer, a PVB photoplate layer as well as a figured glass layer which are mutually spliced from bottom to top. The light-transmittance-adjustable single crystal silicon cell assembly provided by the invention can improve indoor comfort level when being used for BIPV (building integrated photovoltaics) (photovoltaic constructions).

Description

Technical field: [0001] The invention relates to a monocrystalline silicon battery component with adjustable light transmittance. Background technique: [0002] The light transmittance of traditional monocrystalline silicon cell modules is not adjustable. It is either opaque or transparent. It cannot change with the change of ambient temperature. When it is used as BIPV (photovoltaic building), it will affect Indoor comfort. Summary of the invention: [0003] The purpose of the present invention is to provide a monocrystalline silicon cell module with adjustable light transmittance, which can improve indoor comfort when used as a BIPV (photovoltaic building). [0004] A monocrystalline silicon battery module with adjustable light transmittance, which is characterized in that it includes at least a bottom-up battery module backplane, a PVB film layer, a photosensitive intermediate film layer, a PVB film layer, and a single crystal silicon battery that are mutually bonded together S...
