Dioctylquinacridone di(cyanoimine) CN-DOQA was synthesized according to previously reported method. CN-DOQA having suitable HOMO_LUMO energy levels due to _CN groups as electron withdrawing groups was used in organic solar cells as an acceptor in a blend with poly (3-hexyl thiophene) (P3HT) as donor. The photovoltaic devices have shown reasonable high open circuit voltage (Voc) although solar cells have not been fully optimized. Photovoltaic study was supported by thermogravimetric analysis (TGA), dynamic scanning calorimetry (DSC) of CN-DOQA and morphological study of the blend films by atomic force microscopy (AFM).
