Abstract：

We　present　a　self-cleaning　organic　solar　cells　(OSCs)　with　a　light-trapping　structure　by　introducing　a　groove-shaped　micro/nanostructured　haze　thin　films　(GHFs).　The　GHF　with　periods　larger　than　wavelengths　of　incident　light　can　broaden　the　effective　optical　paths　and　promote　the　diffused　lights,　while　keeping　high　(low)　total　transmission　(reflectance)　properties.　When　laminated　GHF　on　top　of　the　light-in　side　of　OSCs,　the　power　conversion　efficiency　of　OSCs　is　improved　more　than　10%.　Simultaneously,　the　superhydrophobic　GHF　composed　of　the　groove　structure　allows　the　droplets　to　successfully　remove　dust　particles　from　the　polydimethylsiloxane　(PDMS)　surface　during　the　roll-off　process　of　the　drop.　Under　10　cycles　of　dust　contamination　and　cleaning　treatment,　OSCs　with　GHF　can　still　guarantee　an　initial　efficiency　of　84%　(76%),　showing　great　potentials　of　OSCs　in　practical　applications.　©　2019　Author(s).
