Quantum-dot Sensitized Organic Photodetectors for Imaging Applications

Seminar: Solid State Technology and Devices | February 1 | 1-2 p.m. | 521 Cory Hall

Speaker/Performer: Dr. Oliver Schmidt, Siemens AG, Corporate Technology, Erlangen

Organic semiconductors are attractive materials as active elements for a
variety of optoelectronic devices, such as light emitting diodes, solar
cells, and photodiodes. In particular the high charge separation efficiency
obtained with an interpenetrating donor-acceptor heterojunction was key for
cost-efficient and large scale fabrication of organic solar cells and
organic photodiodes (OPDs). Here, we will demonstrate that OPDs are
promising detector elements for large area optics-free systems in industrial
sensing and medical imaging applications. The spectral sensitivity of OPDs
can be tailored by adding nanoparticles to cover the range from the visible
to the infrared and even into the x-ray regime.
