In recent years, highly flexible solar cells have been gathering great interest as a power source for
operating wearable and/or on-skin electronic devices which are necessary technologies for the Internet
of things (IoT) society. By adapting such flexible solar cells, wearable and on-skin devices can be free
from the troubles of replacement of batteries and contact problems of external wirings. In this paper, our
approaches for ultra-thin organic solar cells will be introduced with three important keywords, namely
“high power conversion efficiencies”, “strethchability/flexibility” and “robustness against the
environmental conditions”.
