OPTOELECTRONIC DEVICE COMPRISING PEROVSKITE PATTERN AND METHOD OF FORMING THE SAME

摘要

A photoelectric device including a perovskite pattern and a method of forming the same are provided. The photoelectric device includes a substrate, a lower electrode disposed on the substrate, an electron transport layer disposed on the lower electrode, a perovskite pattern disposed on the electron transport layer and including an organic hybrid perovskite, A hole transport layer disposed on the perovskite pattern, and an upper electrode disposed on the hole transport layer. The method for forming a photoelectric device includes the steps of forming a lower electrode on a substrate, forming an electron transport layer on the lower electrode, forming a perovskite pattern including an inorganic hybrid perovskite on the electron transport layer Forming a hole transporting layer on the perovskite pattern, and forming an upper electrode on the hole transporting layer.
