In　this　paper,　we　reported　a　low　temperature　processed　planar　heterojunction　perovskite　solar　cell　employing　silver　nanowires　as　the　top　electrode　and　ZnO　nanoparticles　as　the　electron　transport　layer.　The　CH　3　NH　3　PbI　3　perovskite　was　grown　as　the　light　absorber　via　two-step　spin-coating　technique.　The　as-fabricated　perovskite　solar　cell　exhibited　the　highest　power　conversion　efficiency　of　9.21%　with　short　circuit　current　density　of　19.75　mA　cm　-2　,　open　circuit　voltage　of　1.02,　and　fill　factor　value　of　0.457.　The　solar　cell＇s　performance　showed　negligible　difference　between　the　forward　and　reverse　bias　scan.　This　work　paves　a　way　for　realizing　low　cost　solution　processable　solar　cells.　©　2016　Elsevier　B.V.　All　rights　reserved.
