Nanoident Technologies, the Austria-based printed semiconductor manufacturer says it has delivered the world’s largest printed semiconductor-based photodetector array on a flexible substrate.
The array was manufactured at the company’s plastic electronics fab. 
“One of our industrial customers came to us requesting a radical new photodetector array design for a specific industrial application that could not be delivered with silicon,” said Klaus Schroeter, CEO of Nanoident. “Working together, we were able to deliver the industry’s first large-area array on a flexible substrate that includes specific spectral sensitivity and meets other application-specific requirements.”
The sensor array is built on the 
company’s version 2.0 platform which it said will support the manufacture of large-area photodetector arrays by depositing thin layers of conducting and semiconducting inks onto a plastic foil substrate.
The printable semiconductor technology supported the fabrication of an array 18x12cm in size. “It can easily produce detectors up to 50x50cm or larger,” said the company.
Likely applications for large-area photodetector arrays include industrial measurement and test, medical imaging and security screening.
