HOLE-TRANSPORT MATERIALS FOR PEROVSKITE SOLAR CELL AND THE MANUFACTURING METHOD THEREOF AND THE PEROVSKITE SOLAR CELL COMPRISING THE HOLE-TRANSPORT MATERIALS

摘要

The present invention relates to a hole transport material for a perovskite solar cell, a manufacturing method thereof, and the perovskite solar cell including the same. The hole transport material for a perovskite solar cell of the present invention does not need a dopant and is not environmentally harmful, has excellent device stability, and simultaneously does not decrease a performance of a device due to a batch-to-batch molecular weight variation. Additionally, a manufacturing process is simple and easy, and the performance of the device is excellent.
