In a photovoltaic process light absorption is just the first step; it produces a splitting of the electrons and holes quasi Fermi levels EFn and EFp, respectively. The difference between these two levels is the maximum free energy available, but it can only be used to produce work after the second photovoltaic step, the charge separation.

The working principle of Perovskite Solar Cell is shown below in details. In a PV array, the solar cell is regarded as the key component . Semiconductor materials are used to design the solar cells, which use the PV effect to transform solar energy into electrical energy [46, 47].
In the case of PSCs, the nucleation and crystal growth processes of the perovskite layer are influenced by the contact in which the perovskite is deposited, even if the same deposition procedure is employed. In this sense, it is difficult to decouple the effect of the contact and the effect of the change of morphology.
Each component layer of the perovskite solar cell, including their energy level, cathode and anode work function, defect density, doping density, etc., affects the device's optoelectronic properties. For the numerical modelling of perovskite solar cells, we used SETFOS-Fluxim, a commercially available piece of software.
The studies on perovskite solar cells with a planar heterojunction structure contribute to the understanding of the mechanisms of light absorption and electron-hole separation and enhance the flexibility of device optimization for the development of highly efficient laminated perovskite solar cells.
Theoretical studies will not only help to further improve the performance of perovskite solar cells but also provide ideas to develop simpler and/or more efficient new materials and structures. In a word, all the above issues need to be addressed before making full application of the perovskite solar cells technology.
This fact was confirmed in more detail when Jeffrey A. Christians et al. showed that altering the crystal structure has a significant impact on the cell's stability and the existence of constituent layers around the perovskite layer.
