The A-D-A architecture has been proved quite successful for oligomer-like molecules used for both donor and acceptors in OPV. In this talk, the recent process from our group will be presented for these molecules used for both single junction and tandem cells. Our understanding for the reasons behind the success of the A-D-A architecture and recent modelling for the practical OPV performance limit will also be presented. With both material and device optimization, a PCE of 17.4% of tandem cell has been achieved. These result indicate that OPV has much more potential than previously thought.
