SOLAR cells enabled by large-scale spray coating of nanocrystalline perovskite INKS
Of National scope. With a Public character. It has been granted under a regime of Competitive.
Decarbonization is probably the major goal of the ecological transition. This means that we need to find and develop alternatives to fossil fuels (coal, oil, or gas) to meet the increasing demand on energy production worldwide. Several renewable energy technologies exist, among which photovoltaics (PV) is one of the most promising for the next decades. In the last few years, metal halide perovskites have revolutionised the PV research field. Indeed, record efficiencies have rapidly risen and reached those of silicon PV, which has been developed for about 50 years. Nevertheless, it is important to note that these record efficiencies occur on very small-area devices at laboratory-level. Thus, there is an urgent need for upscaling of perovskite PV. Currently, most perovskite solar cells are fabricated via spin-coating techniques, which are not suitable for upscaling. There exists thus a major bottleneck for the efficient implementation of this technology in a large scale, as needed for the ecological transition. SOLARINKS will address this issue by developping large-area deposition of perovskite PV solar cells through spray-coating of presynthesized nanocrystalline inks. In short, different metal halide perovskite quantum dots with tunable bandgaps will be synthesized by colloidal chemistry approaches with short ligands. These quantum dots will be redispersed in different solvents to serve as inks. A recently-developped automated spray-coater will then make use of th
