Crystallinity Switches Organic NIR Photodetector From Conduction to Photogain

0 points · first seen 19h ago · 1 outlet · 0 comments

Organic NIR photodetector research from ICMAB-CSIC in Barcelona reveals that annealing Y6 thin films above 200 degrees Celsius switches the detection mechanism from basic photoconduction to amplified photogain, producing 127 A/W responsivity in a single-component, blade-coated organic sensor competitive with established hybrid photodetectors in the same spectral window. — Tech Times
