Perovskite solar cell technology is considered a thin-film photovoltaic technology, since rigid or flexible perovskite solar cells are manufactured with absorber layers of 0.2- 0.4 μm, resulting in even thinner layers than classical thin-film solar cells featuring layers of 0.5-1 μm. Comparing both technologies provides an interesting contrast between them.

On the other hand, the operating mechanics of silicon solar cells, DSCs, and perovskite solar cells differ. The performance of silicon solar cells is described using the dopant density and distribution, which is modelled as a p-n junction with doping. The redox level in electrolytes impacts the output voltage of a device in DSCs.
At the time of writing, the keyword ‘perovskite solar’ does for example find over 19,000 papers in the Web of Science, making it essentially impossible to keep up to date with the literature. The perovskite field could thus be said to have a data management problem at an aggregated level.
