The organic photovoltaic cells (OPVs) were fabricated using the polymers and [6,6]-phenyl-C61-butyricacidmethylester(PC[60]BM) as a donor and an acceptor, respectively. The effect of O2 on device stability was examined by keeping the P3HT and BDT-3T devices in N2 and air and the humidity was controlled by introducing getter on encapsulation of device. The experiment was done until thousands of hours. The device stability of new copolymer BDT-3T was comparable to that of P3HT. In this presentation, the device stability of poly(3-hexylthiophene) P3HT and poly(benzo[1,2-b:4,5-b’]dithiophene-alt-terthiophene (BDT-3T) will be discussed in order to understand stability and degradation in organic photovoltaic cells (OPVs). |
