During surface, tin layers can directly reflect away sunshine, and this part sunshine can not be utilized by cell panel, cause luminous energy
Waste.
There is part welding body to be used for reflection light provided with striated structure, but welding base material is copper material bar in processing
Line structure is difficult to microstructure, and reflective surface is unsatisfactory, Tu Xihou, and it is uneven to easily cause tin thickness, easily causes battery
The fragment of piece, tin raw material price is high, blocked up to cause serious waste.
In publication No. CN103413861A patent document, disclose one kind and be used for photovoltaic module light reflecting membrane, its table
Layer is provided with the microstructured layers of prism-like, simple in construction, cost is cheap, can improve the efficiency of light energy utilization of photovoltaic module, but due to micro-
Prism structure crest line is along welding length direction, and the light of reflection can only reflex to the regional area of cell piece, not fill
Divide and utilize full wafer cell piece.
The content of the invention
It is contemplated that at least solves one of technical problem in correlation technique to a certain extent.
Therefore, it is an object of the present invention to propose a kind of reflective membrane in photovoltaic module string spacing/piece spacing,
The insulating barrier can further increase the reflector efficiency of reflector layer, and then further improve the efficiency of light energy utilization, increase photovoltaic group
The power output of part, so as to reach the effect of insulation synergy；Pressure sensitive adhesive pastes the work(to solve battery strings/cell piece spacing
The problem of needing heating during energy film, pressure sensitive adhesive can also lift the efficiency in mould release membrance application process.
A kind of reflective membrane in photovoltaic module string spacing/piece spacing according to embodiments of the present invention, including：
Mould release membrance；
