Double glass component is the development of the photovoltaic modules future large-scale household too

Photovoltaic double glass component is in a traditional single glass components after a new component of the development of packaging technology, consists of two pieces of glass, EVA resin layer and a solar cell, the cell between the wires together in series, in parallel to the pins of the photovoltaic cell components

photovoltaic double glass component is developed after traditional single glass component of a new type of component packaging technology. It is a photovoltaic battery module, by two pieces of glass, ethylene - Of vinyl acetate copolymer and solar battery, through the conductor will they series and parallel to the pins. In global warming and fossil energy, under the background of non-renewable energy sources dried up, with wind, solar and biomass can represent the renewable energy development and utilization of more and more get the attention of the international community. Vigorously develop renewable energy has become the consensus of all countries in the world, it is imperative to develop renewable energy. Among various kinds of renewable energy, solar energy with its green, clean, safe, abundant and an inexhaustible obvious advantages attracted the attention of government and industrial capital. In the past ten years, it has achieved rapid development. In terms of new photovoltaic power generation capacity, China for many years have been the first in the world. However, at the same time, the quality of the photovoltaic modules defects exposed gradually. Some pv components exist in the process of operation maintenance PID attenuation, power generation efficiency decline, snails, crack, back the problem such as craze, has caused great concern in the industry. According to the research of the industry in the relevant institutions, these problems are mainly related to traditional photovoltaic module of the limitations of single glass ( Such as the back high water permeability, poor ability to resist deformation, aluminum frame is easy to cause the PID, etc. ) 。 ) , this need to solve from the product structure design. Compared with the pv single glass module, double glass module to replace the thermoplastic polyurethane, thermoplastic elastomer, such as polyester plastic with glass back on the back. Therefore, the double glass module in service life, power generation efficiency, PID decay resistance, crack resistance, water permeability, insulation, fire resistance, resistance to dust, acid-proof alkaline, etc than ordinary single glass module has more obvious advantages, is one of the main development direction in the future pv module.
