Abstract Bio-optoelectronics necessitate stable and transparent conductors for precise and consistent output of electrical signals. However, diverse aqueous environments challenge the long-term stable operation. In this study, we show a solution-processed transparent conductive nanomembrane that can be directly deposited on human skin and organic substrates, exhibiting good stability in multiple aqueous environments including rainwater, seawater, and biological fluids.

Abstract Hole-conductor-free printable mesoscopic perovskite solar cells, fabricated by infiltrating perovskite into the preprinted porous TiO2/ZrO2/carbon triple-layer scaffold, offer an approach for the industrial production of photovoltaic panels. Here we introduce a reactive post-processing strategy using hexamethylene diisocyanate to enable efficient collection and transport of holes from the perovskite to the carbon electrode.

Relieving strain on silver nanowires embedded in polyimide films for efficient flexible organic photovoltaic modules† Embedding silver nanowires (AgNWs) into polymer substrates is an effective strategy for achieving highly efficient transparent electrodes. However, scaling up the embedded electrode from small areas to a large scale remains challenging, as the strain induced during the drying process of the polymer substrate deteriorates conductance.
