A fullerene-azothiophene donor–acceptor dyad is proposed as a photoactive material for organic solar cells. The photophysical characteristics and the structural properties of films of the dyad are investigated with time-resolved EPR (TREPR) and X-ray diffraction measurements. Solar cells made from the dyad were fabricated and their photovoltaic performance evaluated in function of the active layer thickness.

Abstract
A fullerene-azothiophene donor–acceptor dyad is proposed as a photoactive material for organic solar cells. The photophysical characteristics and the structural properties of films of the dyad are investigated with time-resolved EPR (TREPR) and X-ray diffraction measurements. Solar cells made from the dyad were fabricated and their photovoltaic performance evaluated in function of the active layer thickness.
