Abstract:
The present invention relates to a method for preparing a perovskite compound usable as a light absorber of a solar cell, and provides a method for preparing a light absorber of a solar cell in which the crystallinity of a perovskite compound is increased, resulting in an increase in the stability and efficiency of the solar cell.

Claim (Index 1):
A method for preparing a light absorber of a solar cell, comprising the steps of:\n applying, on an electrode, (a) an adduct of i) a compound represented by Chemical Formula 1, and ii) a polar aprotic solvent containing a NH or NCH 3  structure, and (b) a solution containing one or two types of compounds represented by Chemical Formula 2 (step 1); and heat-treating the electrode of step 1 (step 2):\n MXX\u2032\u2003\u2003[Chemical Formula 1] \n in Chemical Formula 1, M is a divalent metal cation, X and X\u2032 are each independently the same or different halogen;\n AX\u2033\u2003\u2003[Chemical Formula 2] \n in Chemical Formula 2, A is an organic cation of R 1 R 2 R 3 R 4 N + , or (R 5 R 6 N\u2550CH\u2014NR 7 R 8 ) + , wherein R 1 , R 2 , R 3  and R 4  are each independently hydrogen, or Cl 1-10  alkyl, with the proviso that at least one of R 1 , R 2 , R 3  and R 4  is C 1-10  alkyl, R 5 , R 6 , R 7  and R 8  are each independently hydrogen, or C 1-10  alkyl, and X\u2033 is halogen.
