Période du rapport: 2020-06-01 au 2022-05-31
Hybrid organic-inorganic solar energy has grown fast in popularity over the last decade, and it is a rising star among new clean energy sources that are projected to play a key role in optimizing the energy structure and improving the environment. Stability and lead toxicity are now the two key challenges impeding the development of perovskite solar cells.
The project's main goal is to improve device attributes through interfacial engineering, particularly with two-dimensional materials.
Two-dimensional materials have a wide range of nanotechnology uses. Despite their outstanding chemical stability and semiconductor characteristics, 2D materials' poor film-forming capabilities and low vertical conductivity limit their use in electrical devices.
The project's second goal is to use the self-assembly method to create novel materials to address the problem of low vertical conductivity.
Energy is inextricably linked to our daily lives, and no machine can function without it. The vast majority of present energy comes from non-renewable fossil fuels, yet their use can result in environmental pollution and global climate issues. As a result, entire countries have advocated carbon reduction policies. For example, the EU aims to be climate-neutral by the 2050-an economy with net-zero greenhouse gas emissions and China announces carbon neutral by 2060.
Increasing the use of renewable green energy is a cost-effective sound strategy. Solar energy is the cleanest and most abundant free renewable resource that can be converted into thermal or electrical energy. Because of their unique characteristics and solution processing fabrication technology, perovskite solar cells have advanced significantly among photovoltaic technologies.
However, perovskite devices have been hampered in their industrial application due to concerns with stability and lead toxicity. Under the support of the European Commission, the researcher developed a method to boost device stability via 2D materials, which will help to improve device attributes and contribute to the aim of carbon neutrality.
The overall objectives of the project are shown as follows:
1. Fabricating of high-performance perovskite photovoltaic devices via interface engineering;
2. Extending the use of two-dimensional materials to innovative perovskite devices.
