ElFys was present at SPIE Photonics West 2020, February 1-6 2020, San Francisco, California, US

We were presenting our technology and products for the first time at the SPIE Photonics West event, under the Photonics Finland Pavilion. We were happy to meet lots of potential customers and collaborators. Our CEO, Dr. Mikko Juntunen also gave a presentation of our latest achievements in infrared region in one of the parallel conferences, to be published in SPIE conference proceedings.


The Nordics’ first purely deep tech -focused fund Voima Ventures joins our team.

By applying black silicon to light sensing, ElFys technology is able to record all light rays received thus significantly improving any light sensing application from medical imaging and safety detectors to wearable health tech. We expect to share our first applications and use cases with the public next year. Now our focus is on strengthening our R&D and sales teams to help accelerate our global growth. This means that we have several interesting positions open, so if you feel that our mission is calling your name, please reach out to us!


ElFys black silicon photodetectors were presented at 2019 IEEE Nuclear Science Symposium & Medical Imaging Conference (NSS – MIC), 26 October – 2 November 2019, Manchester, UK

Brookhaven national laborotory presented great research results in IEEE NSS-MIC 2019 conference by using ElFys patented b-si photodetector technology. We are very proud of our detector performance, and very glad to help and contribute to push the detector limitations. This will open new doors to potential research applications. We hope to see you all again next year.

30.08.2018  CEO Mikko Juntunen introduced Black Silicon Photodiode technology to the President of France

During his official state visit to Finland, the French President Emmanuel Macron visited Startup Sauna of Aalto University in Otaniemi Campus to see the Finnish innovation system in action. He was hosted by the prime minister of Finland Juha Sipilä. ElFys Chief Executive Officer Dr. Mikko A. Juntunen was invited to the event by the French Embassy in Helsinki due to ElFys participating in the YEi program of France (see the news of June 11 2019). Mikko introduced the Black Silicon Photodiode technology to the President, gave feedback of the YEi program, and discussed about ElFys interests regarding French partnering and market potential.  The program is co-financed by French Institute in Finland, French embassy in Finland, Business Finland and Business France.


12.07.2018   European Space Agency contracted a technology development project from ElFys

ElFys is proud to announce that we have signed a contract with European Space Agency (ESA) for technology development project “Application of Black Silicon Surface Treatment to Photodiodes and Silicon Drift Detectors”. The goal of the project is to evaluate the benefits of the superior sensitivity achieved with black silicon and induced junction in space applications. In addition to optical characterization, we will also investigate our detectors’ response to X-rays. We are extremely excited to see if our technology can revolutionize also the X-ray spectroscopy measurements. Another equally exciting part of the ESA project will be an extensive environmental and radiation stress campaign. These tests will reveal how well our detectors can tolerate the extreme conditions of space.
