Embodiment Construction

[0026] In an embodiment of the method of manufacturing a photovoltaic vacuum window, the air pressure in the sealed space is not higher than 1 mbar.

[0027] In an embodiment of the method of manufacturing a photovoltaic vacuum window, the laser is a pulsed laser.

[0028] In one embodiment, the laser beam scans in one or two dimensions, and the photovoltaic template and the second glass plate also move relative to the laser beam. The photovoltaic template and the second glass plate can be placed on a two-dimensional X-Y work platform. The speed at which the photovoltaic template and the second glass sheet move together may be 3-10 cm / s.

[0029] The photovoltaic vacuum window provided by the invention can realize tight vacuum sealing and can maintain its vacuum state for a long time. The photovoltaic vacuum window of the present invention not only has the function of solar power generation, but also has excellent heat insulation performance, and realizes extremely high ener...

Abstract

The invention discloses a photovoltaic vacuum window and a production method thereof. The photovoltaic vacuum window comprises a photovoltaic moulding board comprising a first glass plate, a second glass plate and vacuum seals, wherein the first glass plate is used as the surface of one side of the photovoltaic moulding board, the second glass plate faces the first glass plate, a space is formed between the first glass plate and the second glass plate, and the vacuum seals are continuously formed on the marginal areas between the first glass plate and the second glass plate and enable the first glass plate and the second glass plate to be connected with each other along the marginal areas so that the space between the first glass plate and the second glass plate can be the sealed space which maintains the vacuum state, wherein the vacuum seals are formed by the process of laser glass welding, and the process of laser glass welding includes the steps: laser beams are focused on the tightly pressed marginal areas of the first glass plate and the second glass plate so as to weld the marginal areas. The photovoltaic vacuum window produced by the method is applicable to the Building Integrated Photovoltaic (BIPV).

Description

Technical field [0001] The present invention involves solar photovoltaic building components, and specifically involves photovoltaic vacuum windows and its manufacturing methods. Background technique [0002] Solar photovoltaic power generation is one of the important ways to obtain renewable energy that is conducive to the environment.Due to the increase in cleaning, safe, sustainable and reliable energy demand, the photovoltaic (PV) system is rapidly expanding its market in energy and industrial technology development.The film solar cell represents the development trend of photovoltaic technology.Solar batteries (photovoltaic or photovoltaic devices) based on silicon -based film -based film have low cost and facilitate the advantages of large -scale manufacturing integration.The photovoltaic module can replace some building components, so as to partially offset the additional costs of installing photovoltaic equipment on the wall, roof and windows of the building.Photovoltaic B...
