Photovoltaic power generation glass building element and curtain wall

Abstract

The invention discloses a photovoltaic power generation glass building element and a curtain wall. The building element comprises a photovoltaic power generation assembly; a heat insulation plate is arranged on the back of the photovoltaic power generation assembly; a supporting frame is arranged between the heat insulation plate and the photovoltaic power generation assembly, so that a heat dissipation cavity is formed between the photovoltaic power generation assembly and the heat insulation plate; a heat dissipation channel communicated with the heat dissipation cavity is formed in the supporting frame; and a fixing plate is arranged on the back of the heat insulation plate.

Description

technical field [0001] The invention relates to a building component based on cadmium telluride power generation glass and a curtain wall made of the building component. Background technique [0002] With the continuous development of new energy and the increasing demand for urban energy conservation, emission reduction, and green environmental protection, building integrated solar photovoltaics has increasingly become a new trend in solar energy application power generation. The further combination of architecture and photovoltaics is to integrate photovoltaic devices and building materials, which is the so-called BIPV (Building Integrated Photovoltaic) architecture. And general building envelope surface adopts coating, decorative ceramic tile or curtain wall glass, and purpose is in order to protect and decorate building. If photovoltaic devices are used to replace some building materials, that is, photovoltaic modules are used to make roofs, exterior walls and windows of...

Problems solved by technology

The reason is that the heat insulation and noise reduction functions of the modules are always difficult to overcome. At the same time, the safety of photovoltaic modules is also an important consideration, mainly electrical safety and load safety, because there are big problems in the heat dissipation of photovoltaic modules. Lead to easy heat accumulation and bring electrical safety

[0003] In the current BIPV applications, most of them use hollow or laminated layers to solve the heat insulation and noise reduction functions of the building, but the effect is not good. At the same time, there are big problems in the heat dissipation of photovoltaic modules. , leading to easy heat accumulation and bring electrical safety

Moreover, after being made hollow or stacked, the efficiency of the modules will also drop significantly, which will also affect the promotion of real BIPV zero-energy buildings
