The present invention discloses a paste and manufacturing methods of a solar cell using a screen painting technique of the paste. A paste of the present invention comprises an inorganic powder, an organic solvent and a binder, wherein the inorganic power has a tap density of 0.01 - 20 g/cm3. An etching mask pattern formed with the paste of the present invention demonstrates a high etch resistance during an etch-back process for the formation of a selective emitter such that an emitter can be stably formed. |
