Abstract

Provided are a solar cell superfine electrode transfer thin film, manufacturing method and application method thereof. The electrode transfer thin film sequentially includes from bottom to top a substrate, a release layer, a resin layer and a hot melt adhesive layer; the resin layer is formed with electrode trenches therein; the electrode trenches are formed with electrodes therein; superfine conductive electrodes are continuously prepared on a transparent thin film via a roll-to-roll nanoimprinting method, the width of an electrode wire being 2 μm-50 μm, and the width of a typical line being 10 μm-30 μm. Directly attach the superfine electrodes of the hot melt adhesive layer to a solar cell by peeling off the substrate material, and sintering at a high temperature to volatilize the hot melt adhesive layer material while retaining the electrodes, thus the electrodes are integrally transferred, without poor local transfer.
