State on the upper surface of backboard body；
Wherein, each reflective pad pasting bar of transverse direction is orthogonal with each reflective pad pasting bar in longitudinal direction.
Advantageously, the length of the backboard body is 1644mm, and the width of the backboard body is 990mm.
Advantageously, the width of the width of each reflective pad pasting bar of transverse direction and each reflective pad pasting bar in longitudinal direction is
8mm。
Advantageously, the gap between the reflective pad pasting bar of the two neighboring transverse direction is 156mm.
Advantageously, the gap between the reflective pad pasting bar in the two neighboring longitudinal direction is 157mm.
According to a kind of solar cell backboard of the present utility model, pass through the high reflective of the cell piece interstitial site in backboard
Material, the light in cell piece gap is reflexed into glass and EVA interfaces, is re-reflected on cell piece, lift light profit in unit area
With rate, component power is improved.
Additional aspect and advantage of the present utility model will be set forth in part in the description, partly by from following description
In become obvious, or by it is of the present utility model practice recognize.
