Abstract

In this work, we show that it is possible to identify combinations of materials which provide the greatest potential as tandem junctions, and to identify specific combinations of materials and film thicknesses which lead to optimal performance. Using this approach, we have investigated a series of wide-band gap, high open circuit voltage (VOC) photovoltaic polymers as front cells in tandem devices. Using the techniques we have developed, we match these polymers with complimentary low-band gap polymers and rapidly optimize tandem devices. In this way, we have been able to demonstrate tandem devices with PCE of up to 12.8% with a minimal consumption of valuable photoactive materials in tandem device optimization.
