Dual-layered percolative networks of photoactive materials and elastomers for highly-stretchable, efficient organic photovoltaics with strain-induced power enhancement up to 60% strain

Dual-layered percolative systems with (1) polymer donor ( P D ):elastomer and (2) P D :small-molecule acceptor networks in bottom and top layers, respectively, enable intrinsically stretchable organic photovoltaics with excellent mechanical robustness.
