Conductive slurry for preparing conductive grid line, organic carrier and application thereof

The invention discloses a conductive paste for preparing a conductive grid line, an organic carrier thereof and an application of the conductive paste. The organic carrier comprises a first organic solvent, a plasticizer and an optional selected auxiliary agent; the plasticizer comprises a microgel material, and the microgel material has a physical cross-linked three-dimensional network structure formed by swelling a thermoplastic elastomer by a second organic solvent; the polarity of the second organic solvent is weaker. According to the invention, a microgel material formed by swelling a polymer thermoplastic elastomer with an intramolecular cross-linked structure by a second organic solvent with weak polarity is used as a plasticizer, and the microgel particles are continuously swelled and finally cross-linked to form a more stable three-dimensional body type molecule with a physical cross-linked network structure, so that the preparation process is simple; the industrial quantity application is easy; and
