Symposium EL20-Photo and Radiation Detection with Organic, Perovskite and Nano-crystalline Semiconductors

Efficient, sensitive and wavelength-selective light detection has become central to modern consumer electronics, science and technology. Photodetectors based on crystalline inorganic elemental materials are the core of today’s photodetectors and cameras. However, a new trend has begun: next-generation semiconductors such as organics, perovskites, and nanocrystals are now becoming increasingly interesting candidates for low noise and color-selective photodetection as well as radiation detection required for novel applications such as machine vision. These novel semiconductor materials, have many desirable features compared to their inorganic counterparts including room-temperature processing from solution and reduced manufacturing costs, while delivering large area lightweight, flexible devices with strong light absorption, optical and electronic tuneability. New emerging applications for photodetectors require self-powered, cost-effective, highly sensitive and flexible devices, conditions which could be largely satisfied using photodiodes base on these novel active materials. The routes to obtain highly sensitive sensors require to minimise, for example, the dark current as a mean to limit the noise in the devices and to improve performance. The dark current values reported so far in the photo and radiation detectors using organics, perovskites and nano-crystals are several orders of magnitudes larger than what predicted from simple thermodynamic perspective. One of the main ongoing challenges is to understand and minimise the dark/noise current, to increase the temporal response, and to extend the dynamic range.


This symposium will be multi-material platform on next-generation photodetectors and radiation detectors. This will include organic, perovskite, 2D, and nanocrystals, covering visible and infrared light detection extending into X-Ray, UV and far-infrared radiation. There will be foci for new materials, device architectures, and characterisation protocols for photodetectors and radiation detectors. The symposium welcomes abstracts that investigate above-mentioned challenges as well as new approaches for narrowband color detection using organic, perovskites and nanocrystals.

  • Organic photodetectors
  • Perovskite photodetectors
