Organic photodiode for detection of herbicides in water using microalgal photosynthesis

Résumé

The growing interest for monitoring the quality of water has triggered the need of fast, portable and cheap detection systems. To answer this problematic, we developed a lab on a chip for herbicide detection based on micro algal photosynthesis. A blue organic light-emitting diode is used as the excitation source while the resulting algae luminescence is monitored using an organic photodiode (OPD). During the OPD optimization process, a correlation between fullerene acceptor concentration and dark current was supposed. Using a blend of DTS(PTTh2)2:PC60BM without interfacial layers result in dark current lower than 10-6 mA/cm2 at-2 V and EQE higher than 50% in the region of interest.
