That's a great question. I'm not totally sure if this is possible. If it was, I think one-way mirrors would use this technology. For now, it seems like they only work because they only let 50% of the light through + there's a brightness differential between both sides. Perhaps someone more informed about this could chime in.

Yeah, there's no magic material that can violate the second law of thermodynamics, because it's the second law of thermodynamics. One-way mirrors are just partial mirrors with less light on one side than the other.
