abstract = {We evaluate entropy production in a photovoltaic cell that
is modeled by four electronic levels resonantly coupled to
thermally populated field modes at different temperatures.
We use a formalism recently proposed, the so-called multiple
parallel worlds, to consistently address the nonlinearity of
entropy in terms of density matrix. Our result shows that
entropy production is the difference between two flows: a
semiclassical flow that linearly depends on occupational
probabilities, and another flow that depends nonlinearly on
quantum coherence and has no semiclassical analog. We show
that entropy production in the cells depends on
environmentally induced decoherence time and energy
detuning. We characterize regimes where reversal flow of
information takes place from a cold to hot bath.
Interestingly, we identify a lower bound on entropy
production, which sets limitations on the statistics of
dissipated heat in the cells.},
