Description
Technical field
The utility model relates to photovoltaic solar cell field, particularly a kind of solar battery sheet with anti-breaking gate electrode structure.
Background technology
Along with the development of solar battery technology, the conversion efficiency of battery is less than improve, and in order to raise the efficiency further, the improvement of silver slurry has seemed the end.Make a general survey of nearly 3 years electrode design, many thinner, the grid lines at grid line of the front electrode design of battery closeer on set about improving, but when this way can cause printing, the secondary grid line grid that break are on the rise, and cause cell piece electric current to reduce, series resistance increases, and whole battery conversion efficiency reduces.
Utility model content
Utility model object: for technology Problems existing, the utility model provides a kind of solar battery sheet with anti-breaking gate electrode structure, thus improves battery conversion efficiency.
