Mixed halide hybrid perovskite films nominally represented by CH(3)NH(3)PbI(3-x)A(x) (A = Cl or F) are also grown and are shown to reveal interesting trends in the optical properties and photoresponse. Growth of good quality lead-free CH3NH3SnI3 films is also demonstrated, and the corresponding optical properties are presented. Finally, perovskite solar cells fabricated at room temperature (which makes the process adaptable to flexible substrates) are shown to yield a conversion efficiency of about 7.7%.</p>1 aBansode, Umesh, P.1 aNaphade, Rounak1 aGame, Onkar, S.1 aAgarkar, Shruti, A.1 aOgale, Satishchandra  uhttps://library.ncl.res.in/content/hybrid-perovskite-films-new-variant-pulsed-excimer-laser-deposition-room-temperature-dry-0
