| Research Abstract |
We fabricated solar cells whose active layer is constructed from a gel material composed of conjugated liquid molecules and a polymer matrix. Elastic modulus and strain of the gel materials were 0.01 times less than and 100 times larger than those of conventional solid conjugated polymers, respectively. Power conversion efficiency of the solar cells containing the gel layer as an active layer was 0.01% when they were not stretched. The power conversion efficiency of a solar cell using conventional conjugated polymer as an active layer decreases when the device was stretched to 20%. On the other hand, the decrease of power efficiency was not observed in the devices using the gels as an active layer.
