3results about How to "Guaranteed passivation effect" patented technology

This disclosure relates to the field of solar cell manufacturing technology, and discloses a method for fabricating a solar cell and the solar cell itself. The fabrication method includes: providing a substrate layer with a first textured surface; forming an anti-reflection passivation layer on the surface of the substrate layer, the anti-reflection passivation layer conformally covering the first textured surface; laser-treating the anti-reflection passivation layer to form a second textured surface, the second textured surface including multiple micro-recesses; and forming a repair passivation layer on the laser-treated surface of the anti-reflection passivation layer to repair laser damage introduced by the laser treatment, the repair passivation layer conformally covering the second textured surface. This disclosure can ensure the passivation effect of the cell while improving the light-trapping effect of the cell surface.

The present disclosure relates to the technical field of solar cell, and particularly relates to a rounded reagent and a photovoltaic cell and a preparation method thereof. A textured pyramid structure is arranged on a poly removal area of the photovoltaic cell, and the top angle of the top of the pyramid and the bottom angle of the bottom of the pyramid are both rounded. The photovoltaic cell has excellent passivation performance and a double-sided rate simultaneously.

The utility model discloses a new energy automobile workpiece surface pretreatment is with passivation machine, including passivation cylinder, passivation cylinder side is equipped with lifting assembly, and lifting assembly output is equipped with the connecting plate, and the connecting plate bottom swing joint has the connecting column, and the connecting plate top outer wall is fixed with drive motor, and drive motor output is connected in the connecting column top through the shaft coupling, and the connecting column bottom is fixed with the net -like box. The utility model discloses through drive motor drive connecting column and net -like box rotation, make automobile workpiece in passivation liquid sustained rotation, effectively eliminate the contact dead angle caused by traditional static soak, ensure that workpiece each surface and passivation liquid fully react, and the independent chamber is separated through the baffle in net -like box, cooperate detachable net -like and place frame, realize the classified storage of different specifications, type workpiece, avoid confusion while convenient quick taking and placing, and the linkage design of lifting assembly and sealing cover plate, on the basis of preventing passivation liquid splashing, allows net -like box to be completely immersed in liquid level.
