We have studied the templating effect of bis(1,2,5-thiadiazolo)-p-quinobis(1,3-dithiole) (BTQBT) on structure and performance of organic solar cells having the multilayer of ITO/BTQBT/metal-free phthalocyanine (H2Pc)/C60/2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP)/Al. Orientation of H2Pc molecules has been studied by infrared reflection-absorption spectroscopy. The angle between the molecular plane and the substrate surface was 82° for an ITO/H2Pc sample, whereas 32 ° for an ITO/BTQBT/H2Pc sample. The angle depends on the materials below the H2Pc layer. The short-circuit current was increased from 3.97 to 5.45 mA/cm2 by the insertion of the BTQBT layer. This result probably originates from the change in orientation of H2Pc molecules. The power conversion efficiency of the solar cell with the ITO/BTQBT/H2Pc/C60/BCP/Al structure was 1.4 %, whereas that of a cell without the BTQBT layer was 1.1 %. The efficiency was also enhanced by the insertion of the BTQBT layer.
