Dr. Juha Heinonen Wins Best Doctoral Thesis

We extend our heartfelt congratulations to Dr. Juha Heinonen for being honoured with the prestigious Doctoral Thesis of the Year Award. In his remarkable thesis, Heinonen delved into the development of “High-sensitivity photodiodes using black silicon and induced junction” has demonstrated his exceptional expertise and significantly contributed to the field of silicon-based photodetectors. Thesis supervisors are Prof. Hele Savin and Dr. Mikko Juntunen.

Also Juha Heinonen is one of co-founding members established ElFys, Inc. The company, dedicated to the commercialization of these advanced sensors, has already made significant strides, selling to 58 customers across 14 countries, with mass production on the horizon.

The innovative features of ElFys' photodiodes, including superior photosensitivity across multiple wavelengths, low dark current, compact design, enhanced photosensitivity, and optimized electrical properties, align closely with the advancements showcased in Heinonen's thesis. This recognition not only underscores Heinonen's expertise but also shines a spotlight on the cutting-edge solutions offered by ElFys, Inc., poised to revolutionize industries reliant on precise and efficient light detection capabilities.
