The invention provides an organic photoelectric device, comprising an anode, a functional layer, a cathode, and a hole transport layer between the anode and the functional layer, the functional layer includes a photoelectric active layer or a light-emitting layer, and the material of the hole transport layer includes black Phosphorus, the number of layers of black phosphorus is single layer or multilayer, and the lateral size of black phosphorus is 1nm-100μm. The organic photoelectric device can improve the interface charge transfer efficiency and the hole mobility of the bulk phase, thereby effectively improving the performance of the device. The present invention also provides a method for preparing an organic photoelectric device, comprising: providing an anode; preparing a hole transport layer on the anode by coating or printing, then preparing a functional layer on the hole transport layer, and preparing a cathode on the functional layer , that is, to obtain an organic photoelectric device, or provide a cathode; prepare a functional layer on the cathode, and then prepare a hole transport layer on the functional layer by coating or printing, and prepare an anode on the hole transport layer, that is, an organic photoelectric device ; The preparation method is simple and easy to operate. |
