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].
Perovskite materials have been an opportunity in the Li–ion battery technology. The Li–ion battery operates based on the reversible exchange of lithium ions between the positive and negative electrodes, throughout the cycles of charge (positive delithiation) and discharge (positive lithiation).
The initial evolution of perovskite solar cells relied on the charge extracting materials employed. The progress on perovskite solar cell has been characterized by fast and unexpected device performance improvements, but these have usually been driven by material or processing innovations.

With the marriage of perovskite and Si solar cells, a tandem device configuration is able to achieve a PCE exceeding the Shockley–Queisser limit of single-junction solar cells by enhancing the usage of solar spectrum.
As a result, the photocurrent of perovskite top cell is increased to match the current generated by Si bottom cell in the 2T perovskite/Si tandem solar cell. Finally, the tandem cell achieves a high Voc of 1.80 V and thus a PCE of 25.4%. 95 On the other hand, the defects at device interfaces are also harmful to device performance.
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.

A separator is a permeable membrane placed between a battery''s anode and cathode. The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.
