The power conversion efficiency of PSCs has raised from 3.8% [3] in 2009 to 22.10% in 2016. For cells having square area aperture greater than 1 cm² has shown a verified efficiency of 19.6%. This efficiency is almost equal to efficiency obtained in 2017 by thin film CIGS and CdTe which is 21% [43]. Because of tunable band gaps in the solar cell, it can be optimized accordingly to the solar spectrum. Shockley–Queisser efficiency limit can be approached by this solar cell which is about 31% for a 1.55-eV band gap [44].

Perovskite solar cells have enormous potential because of its low manufacturing cost, it has low-energy payback time when compared with other solar cells and high efficiency. The PSC can be made easily and at a very low-cost [32]. Because of this, solar cell can be printed using inkjet printers. Perovskite solar cell can also be used in tandem configuration. In tandem cell configuration with the top layer of perovskite cell and bottom layer of crystalline silicon cell has achieved an efficiency of 29.6% [27].
