Abstract

The invention relates to an organic solar cell and a manufacturing method thereof, and belongs to the field of photovoltaic technologies. The organic solar cell comprises an ITO glass substrate, a novel cavity transmission layer, an organic light absorption layer, an electron transmission layer and a reflection electrode; the novel cavity transmission layer is a MoO3 and fluorescent carbon dot composite cavity transmission layer prepared by a solution method, and the thickness of the novel cavity transmission layer ranges from 10 to 50nm. The novel cavity transmission layer is prepared by preparing an ammonium heptamolybdate aqueous solution, preparing a fluorescent carbon dot aqueous solution, preparing a precursor solution of the novel cavity transmission layer, and preparing the novel cavity transmission layer. The novel cavity transmission layer can improve the charge collection capability of the novel cavity transmission layer, enhance a built-in electric field of the device, improve the open-circuit voltage, and finally improve the energy conversion efficiency of the cell. The solar cell is simple in manufacture method, low in cost and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to an organic solar cell and a manufacturing method thereof. Background technique [0002] Energy crisis and environmental pollution are two prominent problems facing the development of human society today. On the one hand, with the continuous consumption of fossil energy, the fossil energy is facing depletion; on the other hand, due to the large amount of carbon dioxide and other harmful substances caused by combustion, the global warming, greenhouse effect and El Niño phenomenon are becoming more and more prominent, and the air quality is seriously declining. , the ecological environment has been severely damaged. One of the effective ways to solve the above problems is to develop and utilize renewable energy. The photovoltaic industry with solar cells as the core directly converts solar energy into electrical energy, which is one of the cleanest energy available to human ...
