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.
