Problems solved by technology

[0004] Chinese patent publication CN101478010A discloses a double-sided photovoltaic cell curtain wall assembly and its manufacturing method. It adopts EVA sealing and bonding, adopts double glass structure, and has high impact strength, but the adsorption strength between EVA interlayer and glass is low, which does not meet the requirements of building safety glass specifications, and is prone to aging and yellowing, which will affect the appearance of the building.
At present, the lamination equipment of the photovoltaic module factory adopts the conventional one-step vacuum lamination machine, and the ordinary lamination process is prone to produce bubbles, displacement and other undesirable phenomena
Most of the BIPV photovoltaic modules use single-sided crystalline silicon solar cells, which cannot be well matched and are suitable for vertical building structures such as curtain walls and road guardrails.
At present, there is no domestic report that photovoltaic module manufacturers use PVB film to encapsulate double-sided crystalline silicon solar cells on ordinary laminators to make BIPV solar cell modules.

Abstract

The invention belongs to the field of photoelectricity and building materials, in particular to a BIPV (Building Integrated Photovoltaics) solar module and a manufacture method thereof. The BIPV solar module comprises glaze super white tempered glass, a plurality of tiled, arrayed and connected double-side crystalline silicon solar cells and ordinary glaze tempered glass which are sequentially arranged from top to bottom, wherein the double-side crystalline silicon solar cells are packaged between the glaze super white tempered glass and the ordinary glaze tempered glass by adopting a PVB (Polyvinyl Butyral) adhesive film, and all groups of double-side crystalline silicon solar cells are connected through solar curtain junction box strings. In the BIPV solar module and the manufacture method thereof, both sides of the BIPV solar module can accept sunlight, thereby the generating power of a system is indirectly improved, and meanwhile, the method has simple process and low improved cost and can avoid adverse phenomena of bubbles, displacement, cracks, atomization, and the like. The BIPV solar module can be applied to building guardrails comprising curtains, roofs, car roofs, road sound insulation guardrails, and the like and realizes BIPV.

Description

technical field [0001] The invention belongs to the field of optoelectronics and building materials, and in particular relates to a BIPV solar cell module and a manufacturing method thereof. Background technique [0002] With the rapid development of society and economy, the demand for energy is increasing day by day. The depletion of fossil energy and the pollution to the ecological environment seriously threaten the sustainable development of society and economy. Therefore, there is an urgent need to replace it with renewable energy. Solar energy, as an inexhaustible and inexhaustible green renewable energy, has been widely concerned in the world. [0003] BIPV (Building Integrated Photovoltaic, BIPV) is to use the photovoltaic module as an integral part of the building, and at the same time exert its power generation function. Since the combination of photovoltaic power generation modules and buildings does not occupy additional ground and building space, it is the bes...
