Solar photovoltaic modules and building curtain walls

Abstract

The invention relates to a solar photovoltaic assembly and a building curtain wall. The solar photovoltaic assembly comprises a first glass substrate, a solar cell layer, a second glass substrate, a third glass substrate, isolation bars and conjunction boxes. The solar photovoltaic assembly integrates advantages of a photovoltaic module and hollow glass, and adopts the first glass substrate as a light collecting surface; the second glass substrate and the third glass substrate can also carry out secondary or multiple reflections on rays leaked from gaps between the cells in a hollow cavity, so that light passing through the third glass substrate is allowed to be sufficient, and light utilization rate is improved; the building curtain wall formed by the solar photovoltaic assemblies ensures a certain indoor illumination intensity through light passing through the third glass substrate, thereby reducing lighting facilities; and besides, due to shelter of cells, light incident to the room can be reduced effectively, so that use amount of cooling devices can be reduced.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to a solar photovoltaic module and a building curtain wall. Background technique [0002] As the world's traditional energy sources are gradually decreasing and gradually drying up, new energy sources have gradually entered the stage of history, and the photovoltaic industry has therefore entered the world's attention. At present, solar photovoltaic modules have been widely promoted, but the installation of photovoltaic power stations occupies a large amount of land, and my country's own land resources are scarce. Therefore, the construction of photovoltaic power stations and the scarcity of land have become a contradictory community. Nowadays, a large number of high-rise buildings often use glass as the building curtain wall. If photovoltaic modules can be applied to the building curtain wall, it can not only effectively relieve the land tension, but also generate clean energy. [0003...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional way of combining photovoltaic modules with architectural glass is to attach photovoltaic modules to the outside of architectural glass. Since photovoltaic modules are exposed to the external environment, they are easily damaged and have poor safety performance.

Or another kind of photovoltaic glass formed by sandwiching photovoltaic modules between the inner and outer layers of architectural glass. The thickness of the two layers of architectural glass increases, which affects lighting, and the photovoltaic modules sandwiched between architectural glass will block light. Penetration, poor lighting

[0004] In summary, traditional photovoltaic modules have poor safety performance and lighting performance
