I’ll be honest, I know absolutely nothing about the science or the tech itself. It just seems like it would help by reflecting the light back at the panel (like trapping it I guess), instead of just bouncing off once. I’m just curious and this seemed like a good place to ask about it

Two-way mirrors (or one-way mirrors, as they’re sometimes called) don’t let light pass in only one direction. They’re just a piece of glass that’s only *partly* mirrored. They reflect some light and transmit some light, in both directions.
The trick to such a mirror is that it’s installed in a location where one side is very dark and the other side is bright. When seen from the bright room, the reflection overpowers any light from the dark room, and it looks like a mirror. Seen from the dark room, the reflection is negligible compared to the light from the bright room, and it looks like a window.
