Convenient testing device for performance degradation of photovoltaic cell

The embodiment of the invention provides a convenient testing device for performance degradation of a photovoltaic cell, and belongs to the technical field of photovoltaic cell testing. The convenient testing device comprises a mounting plate, a base is arranged at the bottom of the mounting plate, a first gear is arranged at the top of the base, a circular shaft is rotationally connected to the top of the base, and the top end of the circular shaft penetrates through the first gear and is fixedly connected with the bottom of the mounting plate. When the angle of the to-be-detected photovoltaic cell needs to be adjusted, two corresponding air cylinders can be driven, so that the air cylinders drive bottom blocks to move, the bottom blocks drive racks to move, the racks drive third gears to rotate, the third gears drive round rods to rotate, the two round rods jointly drive an empty shell to deflect, and the empty shell drives the to-be-detected photovoltaic cell in the empty shell to deflect; the purpose of a
