| Outline of Final Research Achievements |
In this work, we focus on Ti-alkoxides as electron acceptors in the photoactive layers of fullerene-free bulk-heterojunction solar cells. We show that it is
possible to control the morphology by adjusting the molecular structure and size of the Ti-alkoxides. The short-circuit current density (Jsc) increased to 191 μA/cm2 from 25 μA/cm2 with a maximum, when the phaseseparation structure was continuously formed to within about 20 nm below the exciton diffusion length by using either titanium(IV) ethoxide or isopropoxide as an electron acceptor. Within a thickness of 30 nm, the photoactive layer is not influenced by the electron transfer ability; thus, we demonstrate that the chargeseparation
efficiency is equivalent to that of a fullerene system.
