Doping and performance of organic solar cells

We have pioneered the work quantifying the doping levels in polymer-based organic photovoltaic solar cells. The conclusions is: "The results demonstrate thatthe suppressed (non-Langevin) bimolecular recombination rate and charge collection are not strongly affected by native doping levels in this materials combination."

But please don't get confused. This conclusion only applies to the specific (low) doping range that we have measured. If the films are doped strongly, I suspect that it will negatively impact the solar cell performance - a statements to be proven in the future.

Why do I think this work is significant? Because the impact of classical doping has not yet been widely explored yet in organic semiconductors, while in classical electronics it forms a base of every electronic device.
