Abstract: Provided is a lamination device for a photovoltaic module. The lamination device includes: a conveyor, a vacuum adsorption structure, a vacuum break structure and a lamination wheel. The vacuum adsorption structure is disposed on a first end of the conveyor, and configured to adsorb the photovoltaic module to the conveyor. The vacuum break structure is disposed on a second end of the conveyor, and configured to separate the photovoltaic module from the conveyor. The lamination wheel is disposed above the conveyor. A lamination gap is provided between the lamination wheel and the conveyor. A projection of the lamination wheel on the conveyor is between a projection of the vacuum adsorption structure on the conveyor and a projection of the vacuum break structure on the conveyor.

Abstract: This disclosure provides a method for preparing a CIGS thin film solar cell, including placing a substrate formed with a barrier layer into a sputtering chamber, and forming a doping layer on the barrier layer by sputtering, wherein the doping layer is sodium doped a hetero-molybdenum layer; detecting sodium ion content, and introducing water vapor into the sputtering chamber according to the sodium ion content when the doping layer is formed by sputtering. The method for preparing the CIGS thin film solar cell of the present disclosure introduces water vapor into the sputtering chamber according to the content of sodium ions. The water vapor may ensure the stability after sodium ion sputtering, and the content of water vapor is adjusted according to the sodium ion content.

Abstract: The present disclosure discloses a thread tension adjusting device comprising a body, a tension rod, an elastic element and an adjusting knob. A thread passing eye for inputting a thread is arranged below the body. A tension wheel and a thread passing wheel are rotatably arranged on the body. An adjusting knob is used for adjusting a rotational speed of the tension wheel. The elastic element has one end connected to the body and another end connected to the tension rod. The thread tension adjusting device may ensure stability of tensioning and transmitting of the thread by cooperation between the tension rod and the tension wheel, and improve precision for thread tension adjusting by the adjusting knob. In addition, the thread tension adjusting device may monitor thread breakage by the tension detector, and ensure operating stability and safety of the thread tension adjusting device.
