Photocapacitor aka solar cell and battery combined

This might be useful. A Japanese reseacher has managed to combine
a solar cell and a battery into one structure. They dub it the
photocapacitor. Seems currently that the charging voltage and the
charging-discharge capacity need to be increased to be useful at a practical
level. We can translate that as, “it works, but it doesn’t work well
enough for you to work with at home.” But a very useful step if you ask
me. Can’t wait until these are in mass production which might be
sometime in the next decade… I hope.
