Utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly directly can accesses the 220V ac high voltage of electrical network and the back contact solar assembly of output HIGH voltage.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of ridge of high pressure contact solar assembly, it comprises substrate from bottom to top successively, conductive layer, insulating barrier, back-contact battery lamella, tack coat and euphotic cover plate, back-contact battery lamella comprises the cell piece matrix be made up of several back-contact cell pieces, each back-contact cell piece is provided with two circular cavities at the most, the grid line of its sensitive surface forms positive contact point through hole at its shady face, two cathode contact points are at the most provided with at the shady face of back-contact cell piece.
In the utility model preferred embodiment, each back-contact cell piece is of a size of 52mm*52mm, and use this undersized back-contact cell piece composition cell piece matrix, power loss is few, and cost is low.
In the utility model preferred embodiment, each back-contact cell piece is provided with 1 positive contact point and 1 cathode contact point or 1 positive contact point and 2 cathode contact points or 2 positive contact points and 1 cathode contact point or 2 positive contact points and 2 cathode contact points.Undersized back-contact cell piece arranges two positive contact points or cathode contact point at the most, effectively reduces battery power consumption, raise the efficiency, cost-saving.
The beneficial effects of the utility model are: the utility model not only directly can access the 220V ac high voltage of electrical network, and the DC high voltage of exportable 340V, effective raising component voltage, in addition, back-contact battery lamella adopts manipulator integrated battery sheet matrix expeditiously, effectively avoid the fragment of cell piece, while enhancing productivity, significantly reduce processing step and cost.
Accompanying drawing explanation
