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 method for preparing an insulating layer of a flexible photovoltaic module. The method includes: placing the flexible photovoltaic module on a spraying device, and using a shielding component to shield both side surfaces of the flexible photovoltaic module; performing a first spraying on the sidewall to be insulated of the flexible photovoltaic module to form an insulating bottom layer; performing a second spraying on the insulating bottom layer to form an insulating top layer such that the insulating bottom layer and the insulating top layer constitute an insulating layer; and drying the insulating layer.

Abstract: Disclosed is a photovoltaic assembly, including a cooling platform for supporting the photovoltaic assembly to be cooled; a first high-temperature cloth unit provided on the cooling platform; a vacuum cover for forming a vacuum chamber together with the cooling platform, the vacuum chamber accommodating the photovoltaic assembly to be cooled; a second high-temperature cloth unit provided at a side of the vacuum cover facing the cooling platform; and a lifting bracket for driving the vacuum cover lift or fall. In the above-mentioned photovoltaic assembly, the vacuum cover is driven and lifted by the lifting bracket, and forms a vacuum chamber together with the cooling platform. The vacuum chamber creates a pressure cooling effect for the photovoltaic assembly to be cooled. In turn, the appearance defects may be reduced when the photovoltaic assembly is cooled to the normal temperature.
