A HOLE TRANSPORTING MATERIAL HAVING HIGH HEAT-RESISTING PROPERTY A PEROVSKITE SOLAR CELL COMPRISING THE SAME AND A METHOD OF MANUFACTURING THE PEROVSKITE SOLAR CELL

摘要

The present invention relates to a hole transport material having excellent heat resistance and durability, a perovskite solar cell including the hole transport layer as a hole transport layer, and a method of manufacturing the solar cell. The present invention can provide a perovskite solar cell having a photoelectric conversion efficiency equal to or higher than that of the prior art because a hole transporting layer is formed using a hole transporting material in which a phthalocyanine organic ligand is coordinated to a metal. Further, the present invention is a hole transport material having excellent heat resistance and durability, so that a perovskite solar cell capable of maintaining an initial photoelectric conversion efficiency over a wide temperature range for a long time can be obtained by using it as a hole transport layer. In addition, when the hole transporting material according to the present invention is used, the hole transporting layer can be easily formed by a solution casting process, which is suitable for mass production and can significantly reduce the production cost, thereby securing market competitiveness.
