摘要: Provided is an adduct represented by Formula 1: A.PbY2.Q (1) wherein A is an organic or inorganic halide, Y is F−, Cl−, Br− or I− as a halogen ion, and Q is a Lewis base including a functional group containing a nitrogen (N), oxygen (O) or sulfur (S) atom with an unshared pair of electrons as an electron pair donor. The Lewis base is maintained more stable in the lead halide adduct. Therefore, the use of the adduct enables the fabrication of a perovskite solar cell with high conversion efficiency.
