Problems solved by technology

The first is poor heat insulation: there are three types of energy transfer, radiation transfer, convection transfer, and conduction transfer. When BIPV components are applied to buildings, the heat generated by light and the heat generated by battery components will pass through the conduction effect of the glass. It is directly transmitted into the building, which greatly increases the energy consumption of the building and reduces the power generation efficiency of the battery components (the power generation efficiency of the battery components decreases with the increase of the surface temperature); at the same time, the sound insulation effect of the building is also poor

Abstract

The invention discloses power generation glass for photovoltaic building integration and a preparation method of the power generation glass. The power generation glass sequentially comprises an anti-reflection film coating, a first glass substrate layer, a first adhesive film, a second glass substrate layer, a transparent conductive film, an absorption layer, a back contact layer, a back electrodelayer, a second adhesive film and a back plate glass layer from bottom to top; the absorption layer is made of cadmium telluride; and the heat insulation capacity and the sound insulation performanceof the power generation glass are improved, and the maximum power stabilization time of the power generation glass is shortened.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a method for preparing power generation glass used for photovoltaic building integration. Background technique [0002] Building Integrated Photovoltaies (BIPV) refers to the installation of photovoltaic modules on the surface of the building's peripheral structure to provide power, and at the same time as a functional part of the building structure, replacing some traditional building structures such as roof panels, tiles, windows, building facades, and rain Sheds, etc., can also be made into photovoltaic multifunctional building components to achieve more functions, such as the combination of BIPV with agriculture, fishery, and aquaculture. [0003] The double-wave battery module is also called the first generation BIPV battery module, which replaces the back protection material of the photovoltaic module with tempered glass and uses adhesive film for packaging. This k...
