  Perovskites are promising next-generation absorber materials for low-cost and
high-efficiency solar cells. Although perovskite cells are configured similar
to the classical solar cells, their operation is unique and requires
development of a new physical model for characterization, optimization of the
cells, and prediction of the panel performance. In this paper, we develop such
a physics-based analytical model to describe the operation of different types
of perovskite solar cells, explicitly accounting non-uniform generation,
carrier selective transport layers, and voltage-dependent carrier collection.
The model would allow experimentalists to characterize key parameters of
existing cells, understand performance bottlenecks, and predict performance of
perovskite-based solar panel - the obvious next step to the evolution of
perovskite solar cell technology.
