Renewable energies are important topics in the critical sustainability issues . Among the green energies, solar-driven energies are considered to be promising due to their low-cost, high efficiency, and portability . This study focuses on the series of decoration strategies between oxides (i.e. ZnO and TiOČ2) and metals (i.e. Au and NiP) for the flexible solar energy applications. Composites were fabricated by various electrochemical techniques such as cathodic deposition, co-deposition, and thermal reduction. Mechanisms for the synthesis of composites were clarified and the rules of the trade-off between the oxides and metals were also constructed for the optimization of energy output efficiency. This study, therefore, provides the guidelines for the fabrication of oxide/metal composites by the electrochemical techniques.
