> Why the moon, and what does that have to do with regular photovoltaic efficiency?

Presumably to produce energy at night and avoid the need for storage. Seems like a moonshot, though.

But not with these cells? Not getting it :( Or why does (any) storage thing become only interesting then?

They, like me, read the title as "Photovoltaic", which are solar cells. And the comment was around that presumably. I was also reading the headline and the first comments entirely confused until I read the article and it elaborate that these are "ThermoPhotoVoltaic" cells, which involves heat and ties in to the article's comments about this being used for energy storage.

All around, confusing. I didn't even know we had such a thing.
