Pervskite sun-powered cells certainly stand out from scientists overall because of their fast turn of events and proficiency. In any case, strength is as yet an issue that restricts the development of this innovation. The fabrication and characterization of two-dimensional perovskites of the are presented in this work. Ruddlesden-Popper's family (A)2(MA)n−1PbnI3n+1 (three unique A-site huge cations were researched: A=n-propylammonium, t-Butylammonium or Benzylammonium). The materials' band gap got wider as a result of the modulation of the large organic cations. and improved thermal and moisture resistance, making it possible to manufacture PSCs. The remarkable efficiency of 10.35 percent and superior stability of (BUA)2(MA)2Pb3I10 made it possible to retain 68% of its initial value after 1700 h for devices without encapsulation, despite the fact that the organic interlayers intrinsically reduce the transport properties of the devices and, as a result, lower currents are obtained in the layered systems.
