Abstract
Printable organic solar cells (OSCs) have received much attention because of their attractive advantage such as large scale, lightweight, low cost and facile fabrication process. In these solution-processable OSCs, bicontinuous network structure of phase-separated electron donor and acceptor materials in nanoscale becomes most crucial factor to realize high power conversion efficiency (PCE). The phase separation has been widely investigated with the bulk-heterojunction (BHJ) concept by use of pi-conjugated polymer and fullerene derivative. Small molecular materials also can be a good candidate material for the solution-processable OSCs, however, there are very few reports due to the difficulty constructing the nano scale phase separation despite it has practical advantages such as ease purification and high stability. Here, we demonstrate the new approach for fabricating efficient small molecular OSCs through controlling of phase-separation of binary blend of donor molecules and non-active soft materials. We found that the limited molecular diffusion of donor molecules within highly viscous soft matrix play a key role for the nano-scale phase separation. A 20–30 nm sized BP crystal can be created within a highly viscous matrix (TCTA), and that provides efficient charge carrier generation system showing high PCE of 7.8%.
