TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The composition comprises: 0.1-10 wt.% of the nanoscale metal particle, preferably 2 wt.%, and the nanoscale metal particle has a particle size distribution D50 of 10-1000 nm, preferably 30 nm; 65-85 wt.% of aluminum powder, where the aluminum powder is further replaced by silver powder; 15-25 wt.% of organic solvent of the alcohol ether class, which is diethylene glycol monobutyl ether; and 0.1-6 wt.% of a glass frit comprising the glass frit of lead compound. Preferred Components: The nanoscale metal particle is gold, silver, copper, zinc or lead metal material. In the silicon solar cell module, the substrate is a lightproof substrate or a combination of the transparent substrate and a non-transparent layer, and the substrate is a metal substrate, a glass substrate, and a plastic substrate, the covering plate is the general glass, the tempered glass, the acrylic fabric board, the sheet metal, or the thin plastic plate. The silicon solar cell further comprises: a semiconductor substrate, having a N-type diffused layer (13) and a P-type diffused layer (14) located on it; and an anti-reflection layer, formed on the surface of the N-type diffused layer, where the light incident side electrode and the back side electrode are respectively formed on the surfaces of the N-type diffused layer and the P-type diffused layer. Preferred Method: The ethylene vinyl acetate material is melted by using a high temperature and high pressure process under a vacuum environment, so as to pack the silicon solar cell between substrate and the covering plate, and cover the silicon solar cell in the ethylene vinyl acetate material. EXAMPLE - Typical conductive aluminum paste composition comprised (in wt.%) of: ethyl cellulose (1-3); diethylene glycol monobutyl ether (15-25); thixotropic agent (e.g. hydrogenated castor oil) (0.2-0.5); aluminum powder (65-85); nanoscale metal particle (0.1-10); and glass frit (e.g. lead oxide-boron trioxide-silicon dioxide) (0.1-6).
