With　wearable　electronic　devices　arising,　a　flexible　hybrid　energy　harvester　that　is　capable　to　continuously　harvest　multi-types　of　energy　and　seamlessly　integrate　with　human　body　draws　great　attentions.　In　this　paper,　we　introduce　a　novel　self-cleaning　flexible　hybrid　energy　harvesting　system　which　includes　a　groove-shape　micro/nanostructured　haze　thin　film　(GHF),　a　flexible　power　management　circuit,　and　a　hybrid　energy　harvester　is　integrated　by　a　flexible　organic　solar　cells　(F-OSC)　with　an　autonomous　single-electrode　triboelectric　nanogenerator　(AS-TENG)　via　one　common-electrode.　This　system　allows　for　simutaneously　harvesting　both　solar　and　mechanical　energy　through　two　separate　parts　(i.e.　the　top　F-OSC　and　the　bottom　AS-TENG).　The　flexible　power　management　circuit　simultaneously　utilizes　the　large　current　of　the　solar　cell　and　the　high　voltage　of　the　TENG.　In　addition,　GHF　with　excellent　optical　properties,　large　surface　area　and　super-hydrophobicity　has　been　introduced　into　the　hybrid　cell,　which　serves　not　only　as　a　triboelectric　layer　to　increase　the　surface　charge　density　of　the　AS-TENG,　but　also　as　a　light-trapping　layer　to　improve　the　photoelectric　conversion　efficiency　(PCE)　of　the　F-OSC.　Meanwhile,　GHF　helps　this　device　to　achieve　unique　functions,　such　as　dust-proof,　self-cleaning　and　self-encapsulating,　which　significantly　improve　the　stability　and　repeatability　of　hybrid　power　unit　in　practical　applications.　©　2019　Elsevier　Ltd
