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　CH3NH3PbI3　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.　(C)　2016　Elsevier　B.V.　All　rights　reserved.
