This invention discloses a functional modular ordered perovskite thin film, its preparation method, and a solar cell device. The invention constructs a functional modular ordered perovskite thin film by orderly alternating stacking of two-dimensional and three-dimensional perovskite units. Two-dimensional perovskite unit layers are inserted between two three-dimensional perovskite unit layers. Through the ordered functional units, the two-dimensional perovskite units can confine halide ions within the limited space of the three-dimensional perovskite layers. With the increase in the number of two-dimensional perovskite barrier unit layers, the cyclic migration of halide ions inside the three-dimensional perovskite layer under day-night alternation gradually decreases, thereby enhancing the operational stability of the perovskite solar cell and alleviating device fatigue behavior. Through the orderly stacking of two-dimensional / three-dimensional perovskites and the optimization and matching of the unit structure, it is expected to fundamentally solve many stability problems caused by ion migration.

The utility model belongs to the field of calf determination, especially a kind of calf determination device, the urine of current calf determination device is caused by calf urine scattering to lead to urine erosion weighing sensor, influence measurement accuracy and the problem of calf growth and development, present and propose following scheme, it includes concave seat, weighing sensor, weighing plate, side fence, door body etc., weighing plate is equipped with flow preventer and anti-overflow mechanism.Flow preventer's baffle top is concave, can accumulate calf urine, prevent its inflow into concave seat and contact weighing sensor;Anti-overflow mechanism's overflow pipe can when urine in baffle is too much, it is discharged to box body storage.In addition, baffle is placed on weighing plate, is limited by three limit strips, it is convenient to take down and clean, overflow pipe one end is connected with baffle screw thread, fixed ring and sealing ring improve the connection sealing property.Weighing sensor normal work is guaranteed, ensure that body weight measurement data are accurate, and structure is flexible, it is convenient to clean, prolongs service life, and reduces operating cost.
