ERC Proof of Concept to develop platform for computation using light

Professor Bruno Ehrler and Dr. Agustin Alvarez from the Hybrid Solar Cells group receive an ERC grant from the European Research Council. The researchers will develop a new hardware platform for processing information directly where it is sensed. This approach reduces the need to transfer data to separate processing units, as is typically done on conventional computers. The project ‘Vision with Ionic Spatiotemporal Perovskite Arrays’ (VISTA) is funded with €150,000.

Brain-inspired light-sensing platform

The researchers will build a platform using a material normally used in solar cells, called halide perovskite, and arrange it in a regular pattern like the pixels of a camera, so that it can detect and process light. By taking advantage of the light-driven movement of ions within the material, the platform can store information about how signals change over time. It does so by storing and processing information directly in the hardware, similar to the way the brain works. This approach is known as neuromorphic computing.

The technology enables energy efficient and ultra-fast processing for applications such as smart surveillance, wearable sensors, drones, and autonomous vehicles.

Building on previous research

The VISTA project can build on inventions from a previously funded ERC-project. Group leader Bruno Ehrler: “In this project we used perovskites to make very energy-efficient artificial synapses and neurons, electronic components that mimic how the brain works. Now we want to take it to the next level by building a network of these components, which can directly detect what it sees, without the detour through a computer.”

Natural phenomena ‘hyperuniform disorder’ enables highly efficient, thin silicon solar cells

Silicon solar panels are rigid and heavy, and many rooftops cannot support them. This creates a need for thin, flexible solar cells that can be integrated into building materials. However, making silicon solar cells thinner makes it harder to trap light inside the material. Researchers in the 3D Photovoltaics group found a fascinating way to overcome this challenge using a phenomenon called hyperuniform disorder. They publish their findings in the journal ACS Photonics.

The researchers were able to make highly efficient silicon solar cell materials that are 30 times thinner than conventional ones. They managed to do this by integrating a layer of nanometer sized structures on top of the material. Up close, this pattern looks random, but it is remarkably when you step back: no clumps, no gaps, and no repeating pattern. This is called hyperuniform disorder (or HUD).
