Applying conjugated cyanoacrylic acids as the interfacial modifiers (IMs) of TiO2/poly(3-hexylthiophene) simultaneously increases the short-circuit current and open-circuit voltage of hybrid solar cells. External quantum efficiency spectra demonstrates that the lowest unoccupied molecular orbital of IMs plays an important role in determining the degree of contribution of poly(3-hexylthiophene) excitons to the photocurrent.
