The invention relates to the crystal particle solar battery and its preparation method and includes the conducting substrate, semiconductor crystal particle and transparent conducting layer. The clearance of the semiconductor crystal particle between the conducting substrate and the transparent conducting layer is filled with insulating material to isolate the conducting substrate from the transparent conducting layer. The particles are spread on a plane and stuck on the flexible material with waterproof glue. A half of the particles are covered by the waterproof glue and the other half is naked. We erode the surface of the naked particle to reveal the inner material of the crystals, adhere or weld them on the conducting substrate, get rid of the flexible material and waterproof glue, fill the clearance between the particles with insulating material, erode the oxide layer and nitrided layer on the surface of the crystal particles, reveal the conducting layer and aggradate the upper surface electrode and decreased reflecting layer on it.

According to the anti-skid tooth belt, tooth skidding can be avoided, the belt does not loosen easily, and use is convenient; the anti-skid tooth belt is simple in structure and suitable for automatic large-scale production.

The invention relates to the technical field of magnetic material manufacturing, in particular to a method for continuously producing hot-extruded radiant rings, comprising the following steps: (1) preparing a nano-composite phase quenching strip by using melt quenching technology, and homogenizing processing and crushing to make hot-pressed magnetic powder; (2) add lubricant and mix evenly to obtain the mixture, transfer it to the special extruder hopper, and fill it densely; (3) send it into the continuous hot extrusion mold, enter The hot pressing zone is pressed into a full-density alloy, and then enters the deformation zone to obtain a hot-extruded radiant ring. The invention cleverly puts the hot pressing and thermal deformation of the hot extrusion radiation ring in different sections of the same mold, which solves the problem that the hot pressing radiation ring cannot be produced continuously. The method has high yield and material utilization rate, and the orientation Uniformity, less post-processing grinding, can greatly reduce production costs and operating procedures, and is suitable for automated mass production.
