abstract = {This article presents an extension of the classical
gain/loss analysis of Brendel et al. based on the balance of
free energy in a solar cell. We consider the full balance of
all thermodynamic potentials by separating the excess free
energy into excess chemical and excess electrostatic
potentials. A layer-by-layer analysis of an exemplary
silicon solar cell shows that the different functionalities
of different parts of the solar cell, e.g., the neutral base
and the space charge regions, are well reflected in the
different pictures provided by looking at the thermodynamic
potentials separately. Additionally, we investigate fill
factor losses by insufficient majority carrier collection at
the back contact of the solar cell with two prototypical
passivation layers. Here we show that resistive losses,
i.e., losses in the electrostatic potential can be
distinguished from kinetic losses, i.e., losses in the
chemical potential.},
