Abstract
Although triboelectric nanogenerators (TENG) have been explored as a promising candidate for applications in multi-functional intelligent system, the realization of highly-efficient TENG that synchronously possess reasonable light transparency, high near-infrared reflectivity against solar heat gain and good mechanical flexibility, still remains challenging. Here, we present a reliable strategy that can substantially boost the performance and durability of indium tin oxide (ITO)-free transparent flexible TENG by surface modification via self-assembled monolayers (SAM). Through the modification of Sb2O3/Ag/Sb2O3 electrode and polydimethylsiloxane dielectric layer with SAM of 12-(dodecylphosphonic acid)triethyl ammonium bromide and perfluorinated molecules, respectively, triboelectric charges generation is facilitated due to relatively large work-function difference between the tribolayers. The resulting flexible TENG not only afford record-breaking power density (27.28 W/m2) for ITO-free transparent flexible TENG, but also possess high durability against 5,000 cycles of bending owing to good adhesion at the SAM/substrate interfaces and high robustness of electrode. More encouragingly, the use of Sb2O3/Ag/Sb2O3 electrode endows TENG with both reasonable light transparency and high near-infrared reflectivity, which is beneficial against heat gain from solar radiation. This work showcases a promising route towards realizing transparent flexible TENG with high performance and durability, which represents a new platform for design of next-generation wearable electronics.
