Abstract
Disclosed are a paste and a method for manufacturing a solar cell through screen printing said paste. The paste contains inorganic powder; an organic solvent; and a binder, and the inorganic powder has a tap density of 0.01 to 20 g/cm. An etching mask pattern formed using said paste has good etch resistance in an etch-back process by which a selective emitter is formed, and thus, a stable emitter can be formed.
