Abstract
The invention discloses an organic solar battery based on an ultrasonic annealing process. The battery based on n inverted structure is composed of a substrate layer, a transparent conductive cathodeITO, a cathode buffer layer, a photoactive layer, an anode buffer layer, and a metalanode that are arranged successively from bottom to top. The weight percentage of an electron donor to an electronacceptor to a phosphorsmall molecule material is 1 to 1 to 0.03. The phosphorsmall molecule material is (tbt)2Ir(acac), so that the energy level matching and energy transmission of the active layerare realized well. In addition, the preparation method employs the ultrasonic annealing process, so that the active layer materials are separated further, agglomeration is reduced, and the active layer becomes smooth. Meanwhile, the material separation has a tendency by the ultrasonic wave sent out by a single side and an ordered microstructure is formed, so that the higher charge separation efficiency and improved charge balancing are realized and thus the energy conversion efficiency of the device is improved.
Description
technical field [0001] The invention belongs to the field of organic polymer photovoltaic devices or organic semiconductor thin-film solar cells, and in particular relates to an organic solar cell based on an ultrasonic annealing process and a preparation method thereof. Background technique [0002] The energy issue has always been the biggest hot issue in the world. The development of the world and the progress of mankind are inseparable from energy. However, the rapid development of industry in today's world and the increasing demand for energy in human civilization have made countries all over the world increasingly dependent on energy, making the development of the earth's available resources and the search for innovative new renewable energy sources the top priority of the human century. . Renewable energysolar energy has been widely concerned, because solar energy itself is harmless, clean, inexhaustible, inexhaustible and so on. Studying solar photovoltaic power g...
