Description

A kind of solar battery sheet with anti-breaking grid
Technical field
This utility model belongs to technical field of solar batteries, relates to a kind of solar battery sheet with anti-breaking grid.
Background technology
Along with the development of solar battery sheet, in order to improve battery efficiency, the width of main grid is more and more narrow, the line footpath of secondary grid Equally in the level that challenge is thinner.The effect of solar battery sheet pair grid is to collect the electricity that cell piece surface photovoltage effect produces Son, then collects formation electric current, through secondary grid current to main grid.
In the manufacturing process of solar battery sheet, if because printing is bad between two main grids during printing Secondary grid on have at two or above disconnected grid simultaneously, the cell piece designed without anti-breaking grid will not at the position electric current of two disconnected grid Give and passing through, the most just represent the secondary grid that the two breaks between grid and be in failure state, thus affect the electrical property of cell piece, cause Cell piece efficiency is on the low side.
Summary of the invention
The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that a kind of with anti-breaking grid too Sun can cell piece, this solar battery sheet to solve the technical problem that be how to realize have at two or at two more than break Still can collect on the secondary grid of grid and electronically form current direction main grid, thus improve the efficiency of cell piece.
The purpose of this utility model can be realized by following technical proposal: a kind of solaode with anti-breaking grid Sheet, including substrate, it is characterised in that described substrate is provided with some main grids being parallel to each other, and is provided with between described main grid Some secondary grid being parallel to each other, main grid is mutually perpendicular to secondary grid, is connected by gradual change grid between described main grid with secondary grid, and gradually Change grid are connected the width of one end and are connected the width of one end more than gradual change grid and secondary grid with main grid, and every two adjacent secondary grid are all provided with There are anti-breaking grid.
This is with the solar battery sheet of anti-breaking grid, by arranging gradual change grid between main grid and secondary grid, by increasing capacitance it is possible to increase main The welding pulling force of grid, reduced weldering and caused the fracture of main grid and secondary grid junction;Anti-by arranging on the secondary grid adjacent at two Disconnected grid, it is possible to make to have on secondary grid at two or at two more than disconnected still can collecting of grid electronically form current direction main grid, from And improve the efficiency of cell piece.
In the above-mentioned solar battery sheet with anti-breaking grid, described main grid, secondary grid, gradual change grid and anti-breaking grid are the most logical The mode crossing printing is fixed on substrate.
In the above-mentioned solar battery sheet with anti-breaking grid, the width of described main grid is more than the width of secondary grid.
In the above-mentioned solar battery sheet with anti-breaking grid, the width of described anti-breaking grid is equal to the width of secondary grid.
In the above-mentioned solar battery sheet with anti-breaking grid, the width of described main grid is 0.8-1mm, described pair The width of grid is 0.02-0.04mm, and the width of described anti-breaking grid is 0.03-0.05mm.
In the above-mentioned solar battery sheet with anti-breaking grid, one end that described gradual change grid are connected with main grid is to gradual change grid The one end being connected with secondary grid uniformly diminishes, and it is 0.8-1mm that gradual change grid are connected the width of one end with main grid, and gradual change grid are connected with secondary grid The width of one end is 0.02-0.04mm.
Compared with prior art, this has the advantage that with the solar battery sheet of anti-breaking grid
1, this utility model is by arranging gradual change grid between main grid and secondary grid, by increasing capacitance it is possible to increase the welding pulling force of main grid, subtracts Lack weldering and cause the fracture of main grid and secondary grid junction.
2, this utility model is by arranging anti-breaking grid on two adjacent secondary grid, if having on secondary grid at two or at two more than Disconnected grid, the electric current that secondary grid are collected then can flow away on the anti-breaking grid being connected with secondary grid so that have on pair grid at two or More than at two, disconnected still can collecting of grid electronically forms current direction main grid, so that the partial status that originally may lose efficacy Become effective, thus improve the work efficiency of cell piece.
