Abstract A bioinspired self-cleaning strategy for solar cells has been proposed to enable the automatic removal of dust deposited on surfaces. However, the presence of oil-based sticky residues from volatile organic compounds poses a significant challenge for water-based cleaning methods. In this study, we introduce oil-repelling surfaces capable of self-cleaning in any orientation to address oily dust contamination.
