In further scheme, described sheet metal comprises linking arm, the first support arm and the second support arm, and the first end of the first support arm is connected in one end of linking arm, and the second end is connected in solar cell welded disc; One end of the second support arm is connected in the second end of linking arm, and the second end is connected in described cable.
In further scheme, described the first support arm, the second support arm and linking arm surround U-shaped.
In further scheme, described sheet metal is silver strip, copper sheet or can valve alloy sheet.
In further scheme, the thickness of described sheet metal is no more than 0.5mm.
In further scheme, between described sheet metal and the side of substrate, there is space.
In further scheme, the width in described space is less than 0.5 times of gross thickness of substrate, solar cell welded disc and cable.
In further scheme, the welding manner of described sheet metal and solar cell welded disc and cable adopts resistance welded, ultrasonic bonding, laser welding or soldering.
Compared with prior art, the present invention has the following advantages:
1, because described solar cell welded disc is laminar, cable is laminar and adopts sheet metal stube cable and solar cell welded disc, so it is little and can not affect the gathering volume of solar battery array that connected mode of the present invention connects thickness.
2, because described sheet metal is U-shaped, so sheet metal is easy to weld with solar cell welded disc, cable.
3, because described sheet metal is silver strip or copper sheet, like this, be easy to welding and good toughness, be not easy fracture and guarantee the reliable connection of cable and solar cell welded disc.Because the thickness of described sheet metal is no more than 0.5mm, like this, sheet metal has good flexibility and is convenient to bending shaping.
4,, owing to having space between described sheet metal and the side of substrate, like this, avoid the stress damage sheet metal producing due to variations in temperature.
5, owing to adopting resistance welded, ultrasonic bonding or laser welding, compared with soldering mode, can greatly improve the reliability of solder joint under long-term high low temperature alternation environment.
