Product Detail
High performance ultra fine spherical silver powders for silicon solar battery positive silver paste using.
Solar battery positive(facing sun) silver powders paste is the key material to make the solar cell electrode, mainly composed of conductive function phase silver powders, inorganic binding phase, organic carrier and mixed phase. In the whole process of solar cell production, the three ones are the most basic link of the reasonable structure design, epitaxial growth and process after making.
Silk screen printing and firing process of the solar cell is the final procedure of solar energy battery monomer production, so Its material choice and condition control directly affects the various properties of the solar cell. Therefore, silver electronic pastes is the indispensable materials.
Solar battery positive electrode is a conductive materials ohmic contacting closely with both ends of the p-n junction,which bear the collection of silicon wafer carrier and transported it to the external power.
About the preparation of solar battery positive electrode selecting materials, the general requirements are as follows:
1. To form firm contact with the silicon.
2. Small contact resistance, ohmic contact is the best.
3. Low volume resistance of the electrode, has good electrical conductivity.
4. The electrode on the silicon substrate block area is small, generally less than 8%
5. High collection efficiency.
6. Strong solderability.
7. The cost is lower.
8. Less pollution.
Silicon solar battery positive electrode electronic paste is mainly composed of three parts:
1. The conductive ultrafine metallic silver powder.70-80 wt %. With high photoelectric conversion efficiency.
2. After heat treatment inorganic phase with curing and flux effect. 5-10 wt %
3. When low temperature the organic phase with bonding effect. 15-20 wt %
Ultra fine/Superfine silver powders is the main ingredient in silver electronic pastes, it finally forms the conductive layer electrode. Therefore, the particle size, Morphology, surface modification, specific surface area and tap desity of silver powder have more influence on the paste performance. Silver electronic pastes using silver powders particle size general controlled between 0.2um to 3 um, spherical or approximate.
Hongwu nanometer is professional manufacturer and supplier for ultra fine silver powders in small quantity for researchers and in bulk order for industry groups. Business involved all kinds of aspects: manufacturing, research, development, processing, supplying and after-sales service.
