I'm actually believing the 'debunker' here is wrong, I believe it is a hoax (knowingly or unknowingly) but he's claiming they've built a simple DIY cell. I'm thinking they created a galvanic battery, they talk of using copper and there's no mention of what the casing is made of but IMO looks steel (I doubt in rural Nepal they have readily available aluminium). If it's stainless steel, they've got the three components for a basic lemon battery Copper, Zinc and an acid/electrolyte (in this case table salt). By my guess they've got over 150 cells formed in there (if it's working how I'm suspecting it is), which would easily mean they could get the 9V/18W they're claiming. The 'debunkers' theory on what they're doing is somehow hiding a solar panel under the black craft paper and still getting power, which is absurd, or he's claiming they're using a battery, but the power visibly fluctuates far more than it should from a commercial 9V battery. The simplest explanation is usually the best, and in this case I believe the simplest explanation is ignorance. Copper + stainless steel + salt = battery.
