Abstract
The utility model discloses a wedge-shaped front main grid line for a battery wafer. The front main grid line comprises a main grid line, wherein the main grid line is connected with fine grid lines; the main grid line is in a wedge shape; and the fine grid lines are arranged horizontally. The front main grid line has a wedge shape of which the head is narrow and the tail is wide, so that the requirement required by current can be met, and the manufacturing cost can also be reduced; and more importantly, the shading area of the surface of the battery wafer can be reduced, and the amount of illumination can be increased, so that the aim of improving the conversion efficiency of the battery wafer is fulfilled.
Description
Technical field
The utility model belongs to new energy field, is specifically related to a kind of wedge shape battery sheet front main grid line.
Background technology
Crystal silicon solar energy battery is an a kind of electrooptical device, be generally 5 cun to 6 cun wafer or silicon ingot preparation, and size has increasing development trend; In order to reduce positive shading area as far as possible; Front electrode is wanted well to collect photogenerated charge from sensitive surface and is pooled to the main grid line simultaneously, so the electrode wires resistance is big more, and the power output loss of solar cell is big more; The excessive light-receiving area that means of shading area diminishes, and can cause the battery power output to descend equally.Usually the crystal-silicon solar cell front electrode is designed to the tens of thin grid lines of very thin metal and two to three thicker master metal grid lines compositions; Similar " king " word shape; Traditional main grid wire shaped such as is generally at a bit of wedge shape of one or both ends band of width thick line or lines; The shortcoming of this main grid line design is that the shading area is big, and electrode precious metal material consumption is many, fails to make the resistance of main grid line line to minimize.
Summary of the invention
Goal of the invention: the utility model provides a kind of wedge shape battery sheet front main grid line to the deficiency of prior art.
Technical scheme: in order to achieve the above object; The utility model specifically is achieved in that a kind of wedge shape battery sheet front main grid line, and it includes the main grid line, and the main grid line links together with thin grid line; The main grid line is a wedge-type shape, and thin grid line is horizontal.
Beneficial effect: the utility model is designed to the wide wedge-type shape of the narrow tail of head; Can satisfy the needed requirement of electric current, can reduce manufacturing cost again, but the most important thing is to reduce the shading area on the surface of battery sheet; Increase the quantity of illumination, reach the transformation efficiency that improves the battery sheet.
