The 2D/3D construction of hybrid perovskite interfaces is gaining increasingattention due to their enhanced stability towards degradation withoutcompromising the corresponding solar cell efficiency. Much of it is due to theinterfacial charge transfer and its consequences on the electronic and opticalresponse of the composite system, which are instrumental in the context ofstability and efficiency. In this work, we have considered a case study of anexperimentally motivated 2D/3D interface constructed based on Ruddlesden-Popperphases of (A43)$_2$PbI$_4$ and (A43)$_2$MAPb$_2$I$_7$ hybrid perovskites toenvisage the unique tuning of electronic and optical properties through theassociated charge transfer. The corresponding tuning of the band gap is seen tobe related to a unique charge transfer process between the 2D and 3Dcounterparts of the interface mediated from valence to conduction band edges ofthe composite. We have found that the optical absorption spectra can also betuned by the construction of such a hetero-interface and the emergence of aunique two-peak step feature on the absorption edge, which is not present ineither the 2D or 3D hybrid perovskites. Formation of the composite is found toincrease the spectroscopic limited maximum efficiency for the use of thesematerials as solar cells from $\approx$ 24\% for individual components to$\approx$ 32\% for the composite hetero-structure.
