Abstract: The present invention relates to an organic solar cell for a current-voltage test and a preparation method thereof. The disclosed organic solar cell for the current-voltage test comprises a substrate with a preset ITO pattern, wherein ITO on the substrate with the preset ITO pattern is used as the anode layer, and a hole transport layer, an active layer, an electron transport layer and a cathode layer are stacked successively to form a solar cell. A plurality of cell positions are designed on the substrate in the present invention. Each cell has an independent cathode test site and an anode test site. The distance between the test site of each cell and the cell is kept the same and the distance is short enough; and the cells are distributed evenly on the substrate discretely. The present invention has high substrate utilization rate, high data accuracy and good parallelism.

Abstract: The present invention discloses a biaxial supporting device for a rotary opposed piston engine, comprising a cylinder body, a fixing component, a thick axle and a thin axle; the interior of the cylinder body has a cavity; the fixing component is fixed on the outer side wall of the cylinder body; the thick axle is provided with a through hole coaxial with the first axle hole, and is rotatably connected with the through hole; the thin axle is in transition fit with the through hole of the thick axle, and is rotatably connected with the fixing component. The present invention has simple structure, can effectively reduce a diameter difference of two axles to ensure the relatively small diameter of the thick axle and the relatively high strength of the thin axle, and can effectively realize biaxial support of the rotary opposed piston engine.
