Perovskite solar photovoltaic performance test fixture

The present invention relates to a photovoltaic solar cell performance perovskite test fixture, the main components including a base, the base rubber plate, fixing plate, the fixing plate rubber pad, lead screw, etc., the fixing plate perovskite solar cells fixed to the base rubber grooves on the plate, so that the battery positive and negative, respectively, in close contact with the conductive sheet. The conductive rubber sheet placed on the base plate recess. The fixing plate and the fixing plate is provided with a rubber pad and through a respective aperture holes, wherein the fixing plate is also provided with light passing area adjusting plate insertion holes, the area of ​​light passing through the light adjusting plate disposed in the insertion hole area adjusting plate in light through a graduated area adjusting plate. Beneficial effects: crocodile clip not only reduce damage to the metal electrode or a carbon electrode, and the illumination area may be changed by a perovskite light through the solar cell area adjusting plate. The present invention is of simple structure, easy to operate, ideal for testing optical properties of a perovskite of the solar cell.
