Controlled nanomorphology of PCDTBT-fullerene blends via polymer end-group functionalization for high efficiency organic solar cells

We propose a novel method for the control of nanoscale morphologies of the photoactive layers of organic solar cells by using end group functionalization of p-type polymers. The devices based on the end-fluorinated PCDTBT exhibit a remarkably enhanced efficiency as high as 6.0% without applying any...

Zusammenfassung:We propose a novel method for the control of nanoscale morphologies of the photoactive layers of organic solar cells by using end group functionalization of p-type polymers. The devices based on the end-fluorinated PCDTBT exhibit a remarkably enhanced efficiency as high as 6.0% without applying any post-treatments, additives or optical spacers.
