Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] like figure 1 shown.

[0018] A dimming glass based on solar energy and dimming liquid crystal, which is mainly composed of double-layer light-transmitting glass surface layer 1, liquid crystal sheet 4 and solar thin-film battery 3, wherein the light-transmitting glass surface layer 1 can be low-iron glass 1, Also known as ultra-white glass, it is a kind of high-transparency glass. The solar thin-film battery 3 can be CuInxGa(1-x)Se2 solar thin-film battery (ie CIGS), which has good stability, good radiation resistance, low cost, High efficiency and other advantages; the liquid crystal panel 4 can use NPD-LCD liquid crystal panel, which is a transparent material when it is powered on and opaque when it is powered off. The inner surface of the double-layer light-transmitting glass surface layer 1 is bonded with an EVA adhesive layer 2. The EVA a...

Abstract

The invention discloses dimming glass based on solar energy and dimming liquid crystal. The dimming glass is characterized by mainly comprising double transmitting glass surface layers (1), a liquid crystal sheet (4) and a film solar battery (3), wherein the inner surfaces of the double transmitting glass surface layers (1) are respectively bonded with an ethylene-vinyl acetate (EVA) adhesive layer (2); the film solar battery (3) with a frame structure is clamped between two EVA adhesive layers (2) and arranged along the peripheries of the transmitting glass surface layers (1); the liquid crystal sheet (4) is also clamped between the two EVA adhesive layers (2) and is positioned in the frame of the film solar battery (3); the film solar battery (3) is connected with the input end of a storage battery through a control circuit; the output end of the storage battery (6) is electrically connected with the liquid crystal sheet (4); and a dimming resistor (5) is connected in series in a connecting circuit of the storage battery (6) and the liquid crystal sheet (4). The dimming glass has the advantages of adjustable light, energy conservation, environmental friendliness, high strength and low cost.

Description

technical field [0001] The invention relates to a building material, especially a kind of glass that utilizes solar power to generate electricity to adjust the NPD-LCD layer in the glass interlayer to change the light, thereby achieving the effects of sunshade, sound insulation, energy saving and environmental protection, specifically a kind of glass Dimmable glass based on solar energy and dimmable liquid crystals. Background technique [0002] Glass is an essential material for buildings. While it brings light to the interior, it also causes indoor light pollution to a certain extent. Therefore, people have long wanted a product that can adjust the intensity of light entering the room through glass according to needs. available. At present, traditional light-adjusting products such as curtains and blinds are commonly used in the market to adjust the intensity of light. Due to the use of foreign objects, it will inevitably bring about problems such as large cleaning volume...
