Would slapping a two way mirror on a solar panel increase the efficiency?

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

You don’t need a mirror to cause light to reflect. The glass on the front of a solar panel is already carefully designed to reflect as much light as possible back towards the silicon before it leaves the glass. This is done by controlling its thickness and adding surface textures.
