Hybrid nano-architectures with high electrochemical performance for supercapacitors have been designed by growing hierarchical ZnO NRs@CuS@PEDOT@MnO2 core@shell heterostructured nanorod arrays on ITO/glass substrates. This hybrid nano-structured electrode exhibits excellent electrochemical performance, with a high specific areal capacitance of 19.85 mF cm(-2), good rate capability, cycling stability and diffused coloured transparency.

A solid-state transparent photocapacitor has been prepared for the first time by the use of two transparent electrodes (TiO2 and LiFeO2) and also a transparent ion gel-based electrolyte between them, reaching a transmittance of 57% at λ = 555 nm, a specific capacitance of 2.98 μF cm-2 and a specific energy of 0.54 μJ cm-2.
