In order to study the effects of composition ratio of silver paste and the sintering process on the properties of the silver film after sintering, the effects of different ratios of silver powders, glass powders and organic carrier in silver paste and different sintering temperatures and sintering time on the adhesion force and square resistance of the silver film were studied. The morphology of the sintered silver film was observed by SEM. The results showed that the silver film sintered at 760°C for 6 seconds had better properties after sintering when the ratio of silver powders, glass powders and organic carrier in silver paste was 80:5:15 and the silver powders was composed of spherical silver powders and flake silver powders at the ratio of 94:6. The adhesion force and square resistance of the silver film were 8.25 N and 3.47mΩ /□, respectively.

“…The melted glass dissolved some Ag powder and promoted Ag crystallites precipitation on the silicon during firing process. The size and amount of the precipitated Ag crystallites play a very important role in electron conduction, contact resistance between silver electrode and silicon wafer and electrical properties of solar cells [4][5]. Thus, the glass frits must have optimized properties to act these functions effectively.…”

J. Phys.: Conf. Ser.

In this work, a series of tellurite glass frits has been prepared and used as the silver paste in the Ag electrode of the solar cells. The softening temperature of the glass frits have been characterized by the differential scanning calorimeter. The glass frits G3 has the lowest softening temperature, and the corresponding composition of G3 is 42wt.%TeO2-53wt.% PbO-1wt.%B2O3-4wt.%Bi2O3. The surface and cross-sectional microstructures of Ag electrode and the solar cells have been characterized by the scanning electron microscope. The glass frits with lower softening temperature showed the positive influence due to the dense electrode formation and high strength adhesion force. The electrical properties of the solar cells have been also investigated. The solar cells screen printed the silver paste GP3 had the optimum electrical properties, which can be ascribed to the optimized surface and cross-sectional microstructures of Ag electrode. Therefore, the appropriate tellurite glass frits can well improve the electrical performance of solar cells.

Silver-coated carbon fibers successfully fabricated by a modified electroless plating process were characterized by scanning electron microscope (SEM) and X-ray diffraction analysis (XRD). The electroless plating process was modified by replacing the conventional pretreatment and sensitization steps by only using surface hydroxylation step. And the activation and electroless plating steps were merged into one step. The silver layer was successfully coated onto the surface of carbon fibers under the given coating conditions. The effects of AgNO3 solution concentration and reaction temperature on the conductivity of silver-coated carbon fibers were studied in detail. The results indicated that the optimum AgNO3 solution concentration was 0.05 mol/L, and the optimum range of reaction temperature was from 45°C to 65°C.
