| Abstract(in English) | Organic planar solar cells (OSCs) using amorphous molecular materials with high hole-drift mobilities, tris[4-(2-thienyl)phenyl]amine and tris[4-(5-phenylthiophen-2-yl)phenyl]amine, as donor materials and fullerenes (C_<60> and C_<70>) as acceptor materials were fabricated, and their performance was examined. These devices showed power conversion efficiencies (PCEs) of 1.5-2.2% under AM1.5G illumination at an intensity of 100 mWcm^<-2>. In addition, MoO_3 was found to function as a LiF/Al cathode buffer material. The insertion of a thin MoO_3 layer between Al and LiF prevented the reduction of short circuit current density caused by LiF and improved the performance of the OSCs. Bulk-heterojunction OSCs using films of a mixture of these amorphous molecular materials and fullerene derivatives prepared by a spin-coating method from solution exhibited high PCEs of 3.2-4.1%. |
