Organic photodiode for detection of herbicides in water using microalgal photosynthesis

Abstract : 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.
