The older white paper is very much related, it describes the large power router chips, the MPPT nano-invertor microcontroller chips for individual solar cells are just a recent adddition to our system of line chips.
The video presentation is about the wafer scale integration, a million core giant version of the same microprocessor as the tiny MPPT chips, so they are very much related.
[1] Morphle MNI003 datasheet:
input voltage: 0.01V-6.01V (solar cell or battery input)
