Abstract

The invention discloses a full-carbon-base perovskite solar energy cell and a preparation process. The perovskite solar energy cell comprises a substrate, a transparent electrode, fullerene or fullerene derivative, a perovskite light-absorption layer and a charcoal electrode which are sequentially laminated, wherein the fullerene or the fullerene derivative is taken as an electronic transmission layer, and the perovskite light-absorption layer is prepared by a photovoltaic material having a perovskite structure. And the preparation process comprises sequentially preparing the transparent electrode, the fullerene electronic transmission layer, the perovskite light-absorption layer and the charcoal electrode on the substrate. The full-carbon-base perovskite solar energy cell is advantaged in that the preparation process is simple, cost is low, cell stability is high, and cell industrialization production can be realized.

Description

technical field [0001] The invention relates to an all-carbon-based perovskite solar cell and a preparation process thereof, belonging to the technical field of solar cells. Background technique [0002] With the aggravation of energy crisis, environmental pollution and other issues, people's demand for new renewable energy is becoming more and more significant. Renewable energy includes solar energy, hydropower, wind power, biomass energy, wave energy, tidal energy, ocean temperature difference energy, etc. Among them, solar energy has attracted much attention due to its advantages of reusability, low cost, and inexhaustibility. There are many ways to use solar energy, such as direct use of the heat energy of sunlight, such as commonly used solar water heaters, and the conversion of solar energy into other energy sources before utilization, such as solar cells that convert the light energy of sunlight into electrical energy and then use it. Make use of. Due to the high pr...

Problems solved by technology

[0003] Traditional carbon-based perovskite solar cells usually use titanium dioxide as the electron transport layer. The water and oxygen adsorbed on the surface of titanium dioxide will be oxidized into superoxide negative ions and hydroxide radicals under light conditions. These oxides can quickly make the perovskite layer Decomposition occurs, making traditional carbon-based perovskite solar cells less stable to light
