The application relates to the technical field of photovoltaic device detection, and particularly relates to an integrated detection device for perovskite solar cells. The device comprises a box body, a sample table and an optical imaging assembly, and is integrated with a photoluminescence module, an electroluminescence module and a back light imaging module in the box body. Through the integrated design, the workpiece to be detected can complete imaging in three modes in situ without moving, so that the photoluminescence (PL), electroluminescence (EL) and back light images which are completely registered in spatial position are obtained. The application solves the pain point that the prior art cannot accurately associate materials, electrical defects and physical holes due to the lack of back light imaging, realizes accurate attribution of defect sources, and can realize automatic detection through a cooperative controller, and significantly improves the detection efficiency and the accuracy of analysis.

The utility model discloses a rodent self-administration device which comprises a box body, an injection structure and a control host, a cavity which is used for containing rodents to move and is provided with an opening in the front side is arranged in the box body, a top plate with the adjustable size is arranged at the top of the box body, and a bottom plate with the adjustable size is arranged at the bottom of the box body; the side wall of the cavity is detachably connected with the top plate, and the side wall of the cavity is detachably connected with the bottom plate. An opening is formed in the top plate; the injection structure comprises an injection pump arranged on the outer wall of the box body, a container connected with the input end of the injection pump and used for containing injection, a catheter connected with the output end of the injection pump and used for being implanted into jugular veins of rodents, and a bubble filter arranged between the output end of the injection pump and the catheter. The guide pipe penetrates through the opening of the top plate to enter the cavity; the control host is arranged on the outer wall of the box body and is used for providing power for the injection pump. Compared with the prior art, the experimental space occupied by the dosing cage is reduced.
