Embodiment 1

[0045] A kind of nano glass powder, this nano glass powder is prepared by following method:

[0046] (1) Place a glass frit composed of metal oxides with a particle size of 50 μm in a straight barrel-shaped quartz crucible of Φ40×40, and the glass frit includes 30% SiO in terms of mass percentage 2 , 35% B 2 o 3 , 5% P 2 o 5 , 5% Na 2 O, 5% MgO, 15% Al 2 o 3 and 5% ZnO, and the crucible is placed in a closed evaporation chamber, and the evaporation chamber is evacuated to 10 -1 Pa, and then filled with a mixture of 95% argon and 5% oxygen to make the pressure in the evaporation chamber to 1000Pa;

[0047] (2) Connect electrodes to both ends of the crucible, introduce a large current to heat the crucible, the heated crucible heats the glass powder in the crucible, and continue to connect the current until the glass powder melts. After the center of the glass powder melts, that is Control the size of the current to keep the glass powder in a heat preservation state, and at...

Abstract

The invention belongs to the technical field of material chemistry, relates to nano glass powder and particularly relates to the nano glass powder, a method for preparing same and application. The nano glass powder is made of metal oxide, the granule diameter of the nano glass powder is in a range from 1nm to 100nm, and the granule diameter of the nano glass powder which accounts for 30-70% of total weight is in a range from 10nm to 60nm. A laser-resistance composite heating evaporation method is used for preparing the nano glass powder, the productive rate of the prepared nano glass powder is high, the granule size of the nano glass powder is even, the purity of the nano glass powder is high, and simultaneously, the average granule diameter of the prepared nano glass powder is small. The problem that an ink gun is blocked due to the fact that glass powder of large granule diameters is added in traditional solar cell printing ink is solved effectively.

Description

【Technical field】 [0001] The invention belongs to the technical field of material chemistry and relates to a nanometer glass powder, in particular to a nanometer glass powder and its preparation method and application. 【Background technique】 [0002] In order to output the electrical energy of a silicon solar cell, two positive and negative electrodes must be made on the cell. The electrode is the conductive material that forms a close ohmic contact with the two ends of the battery P-N junction. At present, in the production of solar cells, the solar cells are mainly produced through the process of screen printing, and the screen printing is to attach a template with images or patterns on the screen for printing. Usually screens are made of nylon, polyester, silk or metal mesh. When the substrate is placed directly under the screen with a template, the screen printing ink or paint penetrates the mesh in the middle of the screen under the extrusion of the scraper and is pri...
