NOVELTY - An organically modified electrode paste comprises 5-50 wt.% silver powder, 40-85 wt.% silver-coated graphene powder, 2-8 wt.% glass powder, 0-3 wt.% metal oxide powder and 6-30 wt.% organic carrier. The silver powder is spherical silver powder having particle diameter of 0.5-1.6 mu m and tap density of 3.2-6 g/cm3. The silver-coated graphene powder has silver content of 25-35%, particle size of 0.1-0.6 mu m and tap density of 0.2-1.2 g/cm3. The silver powder and silver-coated graphene powder are organically modified. The modification of silver powder and silver-coated graphene powder involves mixing 0.1 wt.% oleic acid, 0.2 wt.% butyl carbene and 0.3 wt.% silver powder and silver-coated graphene powder, adding alcohol acetate and dodecylamine and continuously stirring at 600 rpm for 0.5 hour to prepare organic modified liquid, oxidizing, crushing, drying at 50 degrees C for 4 hours in oven and sieving. USE - Organically modified electrode paste for solar cell. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of organically modified electrode paste.
