Time-reversal asymmetry surpasses conversion efficiency limit for solar cells
Unlike a multiphotovoltaic cell system where the emitted light is absorbed by a subsequent cell (left), the single cell nonreciprocal photovoltaic converter proposed by Sergeev and Sablon (right) causes emitted light is re-absorbed by the same cell, limiting emission losses without the need for additional PV cells.
