Device model simulation is one of the primary tools for modeling thin film solar cells from
organic materials to organic–inorganic perovskite materials. By directly connecting the …

We propose two approaches to compute the band diagram of highly efficient perovskite
solar cells, both based on the migration of a single-mobile ion (halide vacancies). The first is …

Ideality factors are used to identify the dominant form of recombination in many types of solar
cells and guide future development. Unusual noninteger and voltage-dependent ideality …

Impedance spectroscopy (IS) is a straightforward experimental technique that is commonly
used to obtain information about the physical and chemical characteristics of photovoltaic …

It is highly probable that perovskite solar cells (PSCs) are mixed electronic-ionic conductors,
with ion migration being the driving force for PSC hysteresis. However, there is much that is …

Dynamic hysteresis effects have been long known to occur in the current density-voltage
characteristics of perovskite solar cells, with the ionic migration being identified as the …

Details of an open-source planar perovskite solar cell simulator, which includes ion vacancy
migration within the perovskite layer coupled to charge carrier transport throughout the …

Drift-diffusion models that account for the motion of ion vacancies and electronic charge
carriers are important tools for explaining the behaviour, and guiding the development, of …

The mixed halide perovskites have become famous worldwide due to their rapid
development of power conversion efficiency (PCE) and unique photoelectric properties …

Despite current–voltage hysteresis in perovskite solar cells (PSCs) having been the subject
of significant research over the past decade, inverted hysteresis (IH), although frequently …
