Problems solved by technology

However, the metal electrode gold and silver evaporation process is complicated, the energy consumption is high, and the preparation process needs to be completed within 10 -4 Completed in a vacuum of Pa, this condition can be achieved in the laboratory, but it is difficult to achieve in large-scale production
At the same time, precious metals such as gold and silver are expensive, and the process cost is high, which cannot meet the large-scale large-scale production, and at the same time faces the risk of metal electrodes being corroded by other functional layers.

Abstract

The invention provides a novel superimposed perovskite solar cell preparation method. A first block electrode is composed of a substrate and PEDOT:PSS. A second block electrode is composed of FTO, TiO2, perovskite, Spiro-MeOTAD, and PEDOT:PSS. The two block electrodes are superimposed so as to form the superimposed perovskite solar cell. A Layer I comprises thermally spraying PEDOT:PSS spraying liquid with different amount on a Spiro-MeOTAD film. A Layer II comprises thermally spraying PEDOT:PSS spraying liquid with different amount on a back electrode substrate. According to the superimposed perovskite solar cell, holes generated by the perovskite can be successfully extracted. The superimposed perovskite solar cell is simple in making technology and low in cost. Vacuum is prevented and the substrate can be flexibly transformed. The method is beneficial to flexible design of the nanometer structure of the electrodes and large-scale manufacture of the perovskite solar cells.

Description

technical field [0001] The invention relates to a preparation method of a novel laminated perovskite solar cell. Background technique [0002] At present, 80-85% of human energy supply comes from traditional fossil fuels, such as coal, oil and natural gas, etc. These fossil fuels are unevenly distributed below the surface and have limited reserves. , produces a large amount of greenhouse gases, which is one of the factors that accelerate global warming, and is also accompanied by the production of a large number of environmental pollutants, resulting in serious environmental pollution and threatening human health. Renewable energy is the development direction of future energy because of its sustainability, cleanliness and environmental protection. Among renewable energy sources, solar energy, as a new type of energy source, is considered to be one of the most important new energy sources in the 21st century. [0003] Solar energy is an inexhaustible and huge clean energy. ...
