NOVELTY - Conductive aluminum paste comprises: organic carrier, aluminum powder, glass frit, and nanoscale metal particle. The organic carrier, the aluminum powder, the glass frit, and the nanoscale metal particle are mixed to form the conductive aluminum paste, and addition of the nanoscale metal particle is used to reduce a sheet resistance value of the conductive aluminum paste, and to increase adhesion of the conductive aluminum paste, where the organic carrier is composed of organic solvent, resin, and thixotropic agent.    USE - The conductive aluminum paste is useful: in silicon solar cell module (claimed); and to fabricate electro optical devices.    ADVANTAGE - The conductive aluminum paste increases the electro-optical conversion efficiency of the silicon solar cell by utilizing the nanoscale metal particle that reduces a sheet resistance value of the conductive aluminum paste, and increases adhesion of the conductive aluminum paste.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) fabricating conductive aluminum paste, comprising: mixing organic solvent, resin, and thixotropic agent to form organic carrier; and mixing aluminum powder, nanoscale metal particle, glass frit, and the organic carrier to form the conductive aluminum paste; and    (2) a silicon solar cell module comprising: a substrate; a covering plate, located on the substrate; and a silicon solar cell (1), covered with ethylene vinyl acetate material, and located between the substrate and the covering plate, where the silicon solar cell has a light incident side electrode (11) and a back side electrode, and the back side electrode is made of conductive aluminum paste, and the conductive aluminum paste has nanoscale metal particle mixed in it.
