Method for Producing a Perovskite Layer, Perovskite Layer and Use of the Perovskite Layer

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a novel method for producing extremely thin and precisely controlled perovskite layers, which can be either organic-inorganic hybrid or fully inorganic. The method is based on a solution atomic layer deposition (sALD) process that allows the sequential and controlled deposition of perovskite layers on substrates, resulting in homogeneous, conformal, and stable films. The process can be adjusted to produce films with specific thicknesses ranging from sub-nanometers to hundreds of nanometers and can be applied on various substrate types including planar, porous, structured, or even flexible ones.

• Light-absorbing layer in solar cells, including both traditional and tandem (multi-junction) photovoltaic cells
• Opto-electronic devices such as LEDs and photodetectors
• Sensors and detectors for radiation (e.g., X-ray detectors)
• Catalytic electrodes in electrochemical devices and fuel cells
• Energy storage devices
• Flexible or transparent electronics and solar panels, including indoor PV applications for IoT devices
• Improving the interface adhesion in perovskite-based devices by providing an ultra-thin interfacial layer

BenefitsContent extracted from patent full text and abstract with AI.

• Enables ultra-precise control of layer thickness down to sub-nanometer scale
• Produces homogeneous, highly pure, and conformal perovskite layers without pinholes, even on complex surfaces
• Scalable and reproducible process suitable for large-area and industrial manufacturing
• Low temperature and ambient pressure processing, allowing compatibility with sensitive or flexible substrates
• Minimizes material usage and waste, leading to cost-effective production
• The process can produce both hybrid and fully inorganic perovskite materials, increasing application flexibility
• The films exhibit high stability and purity, with no need for high-temperature annealing
• Can be used to engineer interfaces, improving device performance and reliability in perovskite-based electronics
