Preparation method of electrode grid lines, and photovoltaic (pv) cell

Abstract

The provided is a preparation method of electrode grid lines and a photovoltaic (PV) cell. The preparation method of electrode grid lines includes: S1: providing a substrate, and forming a polymer layer on the substrate; S2: imprinting a first trench on the polymer layer with a first mold, applying first conductive paste onto the polymer layer, such that the first conductive paste fully fills the first trench, and scraping off excess first conductive paste; S3: providing a base material, covering the base material with the polymer layer, and transfer-printing the polymer layer and the first conductive paste onto the base material at a certain temperature and a certain pressure; S4: peeling off the substrate from the polymer layer, and dissolving the polymer layer, leaving the first conductive paste adhered to the base material; and S5: solidifying or sintering the first conductive paste, and forming electrode grid lines.
