Abstract
The invention relates to a solar cell capable of easily collecting a current. A plurality of parallel thin grid lines (2) and a plurality of main grid lines (3) perpendicular to the thin grid lines (2) are arranged on a light accepting surface of the solar cell (1). The solar cell capable of easily collecting the current is characterized in that the thin grid lines (2) located outside the main grid lines (3) extend outwards in a thinner and thinner mode; the thin grid lines (2) located among the main grid lines (3) are evenly distributed; the materials of the thin grid lines (2) and the main grid lines (3) are silver paste. Through the changing of the shapes of the thin grid lines, current collecting efficiency of the cell is improved, the use amount of the silver paste is reduced and the production cost is reduced to a certain extend.
Description
(1) technical field
The present invention relates to a kind of solar battery sheet that is easy to collected current.Belong to the photovoltaic field.
(2) background technology
Mainly by the grid line of sensitive surface, be divided into thin grid line and main grid line during present crystal silicon solar energy battery collected current, thin grid line plays a part main collected current.Under normal circumstances, the more thick more cipher telegram stream of thin grid line collecting effect is better, yet because grid line adopts the silver slurry to be made, production cost is relatively high.
(3) summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of solar battery sheet that is easy to collected current is provided, can reduce the consumption of silver slurry, reduce production costs.
The object of the present invention is achieved like this: a kind of solar battery sheet that is easy to collected current, be provided with many parallel thin grid lines at the sensitive surface of described solar cell piece, and the vertical main grid line of some and thin grid line; The material of described thin grid line and main grid line is the silver slurry.
Be in specifically that the thin grid line in the main grid line outside is from coarse to fine to stretch out, the thin grid line that is between the main grid line evenly distributes.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention has not only improved the efficient of cell piece collected current, and has reduced the consumption of silver-colored slurry by changing the shape of thin grid line, has reduced to a certain extent production cost.
(4) description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the enlarged drawing at I place among Fig. 1.
Wherein:
(5) embodiment
Referring to Fig. 1, the present invention relates to a kind of solar battery sheet that is easy to collected current, sensitive surface at described solar cell piece 1 is provided with many parallel thin grid lines 2, and the vertical main grid line 3 of some and thin grid line 2, described thin grid line 2 is in that the part in main grid line 3 outsides is from coarse to fine to stretch out, and the thin grid line 2 that is between the main grid line 3 evenly distributes; The material of described thin grid line 2 and main grid line 3 is the silver slurry.
Claims (1)
1. solar battery sheet that is easy to collected current, sensitive surface at described solar cell piece (1) is provided with many parallel thin grid lines (2), and the vertical main grid line (3) of some and thin grid line (2), it is characterized in that described thin grid line (2) is in that the part in main grid line (3) outside is from coarse to fine to stretch out, the thin grid line (2) that is between the main grid line (3) evenly distributes; The material of described thin grid line (2) and main grid line (3) is the silver slurry.
