Conjugated small molecules can show excellent performance in bulk heterojunction solar cells. Using a simple solution spinning process, high power conversion efficiencies have been achieved by employing these molecules. As an example, DCAO7T/PC61BM based solar cells exhibit power conversion efficiency values of up to 5.08%, with a short- circuit current density of 10.74 mA/cm2, an open-circuit voltage of 0.86 V, and a fill factor of 55.0%.
