Organic Photodiodes with Thermally Reliable Dark Current and Excellent Detectivity Enabled by Low Donor Concentration.
Chunyang Zhang,Yunhao Cao,Yu Song,Gang Yu,Linfeng Lan,Cheng Zhou,Zhiwei Lin,Lei Wang,Ning Li,Fei Huang,Yong Ming Cao +10 more
TL;DR: In this paper , the authors investigated the effect of donor/acceptor ratio on the performance of organic photodiodes (OPDs) and showed that OPDs with a low donor concentration in the active layer can achieve a very low Jd of 1.68 × 10-7 mA cm-2 at a reverse bias of -2 V, which is almost temperature independent owing to the low polymer content.
