The German Fraunhofer Solar Research Institute has announced a joint research project with the EV Group. They have designed a device and related processes that allow direct bonding of silicon wafers at room temperature, as well as good conductance and light transmission. nature.
The direct bonding technology of this silicon material provided by the German research institute has opened up a new way of thinking. It can enable different materials to be directly bonded together after optimization, which provides a great advantage for the manufacture of multi-junction cells. Good prospects.
The emergence of this technology can easily combine raw lattice mismatched materials such as gallium arsenide and silicon, gallium arsenide and indium phosphide, indium phosphide and gallium, gallium arsenide, and gallium telluride. and many more.
The research organization hopes that this combined technology will play a key role in the preparation of the next-generation three-nothing structure batteries, and they hope that this will greatly benefit the development of space and concentrator cells.
Chopped Graphite/Graphite Electrode in different materials have different definition of graphite pieces, some data and literature is not very big graphite particles are called graphite pieces (such as Graphite Powder) some is graphite products have a certain size, for Graphite Broken into patches, we here say of graphite for a second, usually called graphite blocks. Graphite is produced from graphitization and machining process of graphite products. It is used as additive and conductive material in the manufacture of graphite waste in steel and foundry industries, and can also be processed according to customer's requirements. They are also widely used in electric arc furnaces (steelmaking) and electrochemical furnaces (metallurgical and chemical industries).
Main use of graphite
Graphite pieces due to its low ash content, conductive and heat conduction performance is good, so there are a wide range of USES, can be added to the formula of less ash or dust products, graphite broken broken into small particles commonly use. Ingredients to add a certain amount of graphite, the plastic paste after kneading, especially during extrusion can reduce the friction resistance paste to squeeze the mouthpiece, to improve the coefficient of pressure type. Graphite pieces of coal adsorption properties of asphalt is better, to join the carbon block can rise to reduce the "short" waste (i.e., the product after roasting top produce honeycomb structure), and can improve the thermal conductivity of the carbon block and alkali corrosion resistance. The electrode paste used in hermetically-sealed thermal furnace is added to a certain amount of graphite to increase the conductivity and thermal conductivity of the electrode paste and accelerate the sintering speed of electrode paste. When the graphite is ground into small particles or fine powder, it is also used as raw material for the production of graphite chemical equipment (such as graphite-resin tubes). The graphite can also be used as a carbon addition agent for the electric furnace.
Graphite classification
1. Raw and broken. It is a raw blank that is not qualified after molding.
2. Roasting is the cutting debris that is recovered after the roasting of raw billet and after inspection of unqualified waste and the processing of calcined products.
3. The graphite is broken, and it is inspected by the graphite-producing waste and the cutting debris produced by graphite products in the process of processing.
