In front of the mother is the most commonly used super-light structure, in the solar power battery the light-emitting surface of a transparent substrate as a component of the support plate, under the fill material and the back cover material solar cells sealed. The top transparent glass, Good use of transparency and impact strength are good tempered white glass, the filling material is mainly used in the UV light transmittance attenuation of small polyethylene butyral and good moisture resistance of ethylene vinyl acetate. The use of metal aluminum with polyvinyl fluoride structure dragon sandwich structure, solar power generation has moisture resistance and high insulation.
In addition, the application of a particularly high reliability requirements, the development of a new package, that is, between the two pieces of glass plate with the resin to seal the solar power battery. With the progress of amorphous silicon solar cells, With the same crystalline silicon solar cell super-smooth package, the integrated solar cell substrate glass directly used as a light-receiving surface protection board, solar power generator the unit cell connections do not have wires, so the components can make the assembly process has become particularly simple , Has been in the trial 10-40cm size rectangular integrated solar cells.In addition, the component type is also under study in the future such as the development of a larger area of solar cells to make progress, then a single substrate type of component is more appropriate, This can further reduce the cost of the components.
Large area integrated solar power batteries such as the use of the metal mask shown, wet etching method or dry etching method is more difficult, and the author developed the laser lithography is more effective.Especially the use of excitation. It is possible to make the integrated type amorphous silicon solar cell module from the formation of the transparent electrode to the assembly of the assembly continuously, and this is promising from the standpoint of industrial production of solar cells, Power of amorphous silicon, monocrystalline silicon, polycrystalline silicon solar cell components, which is a single substrate type large area amorphous silicon solar cells.
Lists the amorphous silicon, monocrystalline silicon, polysilicon variety of power with the specifications of solar modules, single crystal solar power battery components and amorphous La solar modules and the relationship between the temperature and the relationship between light intensity, Components and unit cell temperature coefficient is different, because the components include the wiring part of the factors, solar power portable generator the figure shows, amorphous silicon solar modules and monocrystalline silicon solar modules, the output of the relationship between the temperature is small, the conversion The efficiency decreases with the light intensity, and is smaller in the linear range than that of monocrystalline silicon.
