Double-glass solar cell module and system

Abstract

The invention discloses a double-glass solar cell module, which comprises a front tempered glass, a first bonding layer, a solar battery group, a second bonding layer and a back tempered glass which are sequentially stacked from top to bottom; the double-glass solar cell A fixed frame is arranged around the battery assembly, and the fixed frame includes a first bracket and a second bracket that are oppositely arranged, and the inner side of the first bracket and the second bracket is provided with a card slot, and the card slot is used to fix the double glass For the solar battery module, grooves are provided on the outside of the first support, protrusions are provided on the outside of the second support, and the grooves are adapted to the protrusions; the first support and / or the second support The second bracket is provided with a through hole for leading out the positive and negative poles of the double-glass solar cell module. Correspondingly, the present invention also discloses a system using the above-mentioned double-glass solar cell module. By adopting the invention, the assembly is very convenient and simple, the assembly quality can be unified, the yield rate is high, and the component reliability is high.

Description

technical field [0001] The invention relates to the field of solar cells, in particular to a double-glass solar cell component and system. Background technique [0002] The solar battery module is the core part of the solar power generation system. Its function is to convert solar energy into electrical energy, and then send the electricity to the storage battery for storage, or push the load to work. A solar cell is a device that effectively absorbs solar radiation energy and uses the photovoltaic effect to convert light energy into electrical energy. When sunlight shines on a semiconductor P-N junction (P-NJunction), a new hole-electron pair (V-E pair), under the action of the P-N junction electric field, holes flow from the N region to the P region, electrons flow from the P region to the N region, and a current is formed after the circuit is turned on. [0003] Traditional crystalline silicon solar cells basically only use front passivation technology, depositing a laye...

AI Technical Summary

Problems solved by technology

Existing double-glass solar cell modules do not have a surrounding frame, and water vapor is easy to corrode the EVA film, which affects the reliability of the module

In addition, due to the loss of the shaping effect of the surrounding frame, it is easy to cause damage to the components by wind pressure
