AMYS

Advancing Manufacturability of Hybrid Organic-inorganic Semiconductors for Large Area Optoelectronics
Background and main goal
Optoelectronic technologies based on a perovskite semiconductor promise numerous advantages over existing options: a lower levelized cost of solar electricity, colour-pure light-emitting diode displays, and highly sensitive detectors for photons, X-rays, or gamma rays. The challenge is that best-performing perovskite materials still degrade too rapidly to make any of these applications economically viable at this stage of research. Furthermore, performance quickly decreases when increasing the size of devices towards industry-relevant dimensions.

AMYS aims to overcome these limitations by (i) exploring the compositional space of perovskites to find compositions most suited for upscaling, (ii) understanding of how processing conditions can be modulated to improve optoelectronic properties and stability of the resulting thin films, and (iii) advancing the manufacturability of perovskites by demonstrating large-area optoelectronic devices that exhibit high performance and stability.

Idea and approach
Picture
The AMYS project is centred on the identification of novel perovskite thin-film formulations and their deposition on large areas with novel industry-compatible processes. More specifically, AMYS will:
  • Identify most promising hybrid organic-inorganic metal halide thin film compositions and corresponding processing parameters using a high-throughput combinatorial approach,
  • select defect tolerant combinations of precursors and processing parameters that are most suited for upscaling,
  • design manufacturing methods to deposit the most promising perovskite thin films on large flexible substrates or highly textured substrates, and
  • validate the new compositions and thin-film deposition methods by demonstrating efficient and stable devices featuring large dimensions (larger than 200 cm^2).

To accomplish its objectives, the AMYS project will be organised around two 'pipelines' to bring compositions and processing conditions from small thin films to large-area functional devices of industrial relevance:
  • Pipeline 1: Known perovskite compositions and their deposition over large areas on flexible or textured substrates using innovative processes.
  • Pipeline 2: New compositions, from their discovery at high throughput using a combinatorial approach, their validation in small devices up until their incorporation in large-area devices.

Technical challenges
  • Exploration of the rich compositional space of perovskites to identify formulations and processing conditions that result in thin films with suitable optoelectronic properties and operational stability for different applications
  • Development of deposition methods and corresponding process parameters to upscale perovskite thin films on various types of flexible and/or textured substrates to industry-relevant dimensions (>200 cm^2), while maintaining performance and operational stability
