Abstract: Disclosed is a method for preparing the light absorption layer of a perovskite solar cell using the chemical vapor deposition (CVD) method. The method for preparing the light absorption layer of a perovskite solar cell using the chemical vapor deposition (CVD) method includes forming a PbIx thin film on a substrate by means of chemical vapor deposition; supplying methylamine and an iodine (I) precursor on the PbIx (1≤x≤2) thin film and forming a CH3NH3PbI3 thin film having a perovskite structure through heat treatment.
