"oligomer acceptor prepared by the researchers achieved power conversion efficiencies above 15% and an extrapolated T80 lifetime over 25,000 h... inherits the appropriate crystallinity from SMA, but also presents comparable thermal stability to polymer acceptors, contributing to the development of solar cells that combine a high efficiency with a long lifetime... oligomer acceptor appropriate crystallinity from SMA... comparable thermal stability to polymer acceptors"
