In this paper we present a high-quality multilayer graphene electrode fabrication using a simplified layer-by-layer transfer progress.we use highly purified methane as carbon source at 1030℃ to synthesis high-quality monolayer graphene by chemical vapor deposition. The coverage of monolayer graphene is more than 90% and carrier mobility is much higher than 300cm2/Vs with the transparent of 97%.during the transfer process,we use simplified layer-by-layer transfer technology to fabricate high-quality multi-layer(4~5) graphene transparent conductive film and the optical tansmittance of 5 layer graphene tansparent conductive film is high than 87.5%(550nm).The excellent surface and roughness is indicate by AFM and SEM.To further demonstrate availability of 5-layer graphene tranparent conductive,we use electon beam evaporation to prepare high-property solar cells based on P3HT:PCBM transport layer and graphene/MoO3.The analysis of current-voltage characteristic indicates that graphene transparent conductive film obviously improve the solar cells' electical conductivty.
