Double glass module
A double glass module, including a front panel glass (10), a first adhesive film (20), a solar cell pack group (30), a second adhesive film (40), aluminum foil (50), a third adhesive film (60) and a rear panel glass (70) successively stacked. The aluminum foil is added in front of the rear panel glass of a double glass module, and since the aluminum foil has a high light reflectivity, the reflection effect for transmitted light energy is improved, so that the power of the double glass module is significantly enhanced. Meanwhile, since the aluminum foil has a better heat conductivity, the heat generated by the solar cell pack group can be conducted and dissipated in time, so that the temperature of the double glass module is reduced in time, thereby reducing a temperature coefficient impact factor, and prolonging a daily mean efficient power output time of the double glass module.
