It may look much the same but Samsung have made a new Eco Remote Control for its latest Tvs,comprises 28% recycled polyethylene terephthalate and solar cells cells can charge the internal battery. There is also a USB-C port for charging if desired.
This looks super cool. Imagine leaving the remote just next to your window so that it can charge while you go to work or shopping (although it may take some time to charge properly). I have a solar battery pack and I do this all the time (it charges much more quickly in summer though, understandably).
