Abstract
The invention discloses a pattern design for a front electrode used for a solar battery, which comprises main grids and thin grids, wherein the thin grids are laterally distributed on a front electrode, the main girds are longitudinally distributed on the front electrode, the thin grids are connected in pairs by the main grids, and the connecting parts of the thin grids and the main grids adopt triangular structures. According to the pattern design, on a basis of not changing the original macroscopic appearance of a battery piece, through changing the microcosmic design for the thin grids, the condition of poor contact between the thin grids and the main grids can be improved, thereby effectively ensuring the transmission of current, improving the conversion efficiency of the battery piece and improving the printing yield; meanwhile, the cross sections of the main grids can be changed, so that the smoothness of the main grids can be improved, and the welding property is improved. The pattern design is simple in structure, has obvious beneficial effects, is realized easily and is suitable for industrial production.
Description
Technical field

Background technology
Solar energy is a kind of renewable resource of cleaning, solar cell take the PN junction photovoltaic effect as the basis has fine application prospect, the purpose of solar cell surface grid line design is to collect to greatest extent photoelectric current, and reduce as much as possible series resistance, also do not affect simultaneously the battery light-receiving area, be at present coupling high resistant technique, the battery surface grid line design usually adopts and increases the mode that grid line quantity reduces the grid line width and increase simultaneously the grid line height and realize, this is the printing applicability a major challenge to slurry, the rising of empty seal ratio when more and more narrow grid line will certainly cause printing, the situation that this void is broken is if there is the junction at thin grid and main grid, directly have influence on electric current output, cause the conversion efficiency degradation.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiencies in the prior art, the invention provides a kind of transmission that can effectively guarantee electric current, promote the cell piece conversion efficiency, improved the front electrode design of the solar cell of printing yield.
Technical scheme: a kind of front electrode design of solar cell, front electrode is provided with the thin grid of cross direction profiles, described front electrode is provided with the main grid of vertical distribution, described main grid is connected with carefully grid are vertical, the main grid of described vertical distribution joins the thin grid of described cross direction profiles in twos, and described main grid adopts triangular structure or trapezium structure or semicircular structure with thin grid junction.
Described main grid is 0.12mm with the junction length of thin grid.
Beneficial effect: originally be to invent on the basis that does not change the original macro morphology of cell piece, by changing thin grid Micro Instructional Design, improve the situation of thin grid and main grid loose contact, effectively guaranteed the transmission of electric current, promote the cell piece conversion efficiency, improved the printing yield, changed simultaneously the cross section structure of main grid, the main grid evenness is improved, improved welding performance, the present invention is simple in structure, and beneficial effect is obvious, be easy to realize, be suitable for industrialization production.
