Abstract: A hole transporting material having excellent heat resistance and durability, a perovskite solar cell including the hole transporting material in a hole transporting layer, and a method for manufacturing the solar cell are provided. Provided is a perovskite solar cell having PCE which is equal to or greater than PCE in the related art because the hole transporting layer is formed by using the hole transporting material in which the phthalocyanine-based organic ligand is coordinate-bonded to metal. Also, provided is a perovskite solar cell which can maintain initial PCE for a long time in a wide temperature range when the hole transporting material is used as the hole transporting layer due to excellent heat resistance and durability.
