Using self-organizing materials of various molecular shape as smart dopants to the active layer of the organic photovoltaic cells is one of the considered possibilities. Three novel discotic compounds in the non-chiral, homogeneously chiral and racemic modifications are designed. All three materials exhibit the columnar rectangular phase stable over a reasonably broad temperature range. Bulk-heterojunction solar cells based on the new discotic materials and PTB7 and PC71BM were designed and constructed, the resulting power conversion efficiency values are strongly dependent on the molecular structure (non-chiral, chiral, racemic) and specific amount of compound in active layer.
