The disclosed embodiments relate to a dismantling device configured for a frame of a PV module. The dismantling device includes a connection portion, a first holding portion, and a second holding portion. The first holding portion is connected to the connection portion and configured to press against one of an inner wall and outer wall of the frame. The second holding portion is slidably disposed on the connection portion and movably closer to or away from the first holding portion along a sliding direction. The second holding portion is configured to press against the other one of the inner wall and the outer wall so as to clamp the frame with the first holding portion and to distort the frame.

Dismantling device for frame of PV module

A method for removing boron is provided, which includes (a) mixing a carbon source material and a silicon source material in a chamber to form a solid state mixture, (b) heating the solid state mixture to a temperature of 1000&#xb0; C. to 1600&#xb0; C., and adjusting the pressure of the chamber to 1 torr to 100 torr. The method also includes (c) conducting a gas mixture of a first carrier gas and water vapor into the chamber to remove boron from the solid state mixture, and (d) conducting a second carrier gas into the chamber.

A method of manufacturing a metal foil with microcracks includes placing a metal foil between a first material sheet and a second material sheet and then rolling them to form a plurality of microcracks in the metal foil. The microcracks are penetrating, and a sidewall of each of the microcracks is an irregular rough surface. Two ends of each of the microcracks are acute angles. A sound-absorbing structure includes at least one metal foil and a base plate kept at a distance from the metal foil, wherein at least one resonant cavity air layer is formed between the metal foil and the base plate by the distance, and the metal foil has microcracks.
