 The present invention will be further described below in conjunction with drawings and embodiments.
 A solar cell and its component welding performance testing process proposed in the first embodiment of the present invention, passes a certain amount of current to the solar cell or component to change the temperature of the welding area; if the welding is not good, the contact resistance will be large, The temperature change is large, so by collecting the data of temperature change, the welding performance parameters can be obtained by image processing and data processing and analysis software in the computer.
 As shown in Figure 1, the solar cell and its component welding performance tester dedicated to the first embodiment is composed of a current and voltage controller 1, a wire 2, an infrared thermometer 4 and a computer 6, and the current and voltage controller 1 passes through the wire 2 is connected to the solar cell or component 3; the infrared t...
