“…From RT—200 °C, the smaller band energies due to electron shuttling required lesser energy to move from conduction band to the valence band and the reverse is true. The attained band gap energies were in proximity with those reported by other researchers [21, 24]. …”

“…Deraz et al reported the synthesis and characterisation of new copper-based nanocomposite using glycine-assisted combustion method [7] while in his paper (Habibi et al) [21] fabricated and characterised ternary CuO-ZnO-Cu 2 O nanocomposites by Sol-Gel Route at different temperatures [22]. Meanwhile, Sasmal and other produced ternary Cu 2 O-Cu-CuO nanocatalyst with astonishing activities for 4-nitrophenol reduction in aqueous solution and synthesised catalytic Cu/Cu 2 O NPs prepared in aqueous medium [23, 24]. However, as far as we know, there are no green prepared binary/ternary copper-zinc oxide nanocomposites which have been reported.…”

A novel ternary Punica granatum L-Cu/Cu2O/CuO/ZnO nanocomposite was successfully synthesised via green route. In this work, we demonstrate that the green synthesis of metal oxides is more viable and facile compare to other methods, i.e., physical and chemical routes while presenting a potential electrode for energy applications. The prepared nanocomposite was characterised by both microscopic and spectroscopic techniques. High-resolution scanning electron microscopy (HRSEM) and X-ray diffraction (XRD) techniques revealed different transitional phases with an average nanocrystallite size of 29–20 mm. It was observed that the nanocomposites changed from amorphous-slightly crystalline Cu/Cu2O to polycrystalline Cu/Cu2O/CuO/ZnO at different calcination temperatures (room temperature-RT- 600 °C). The Cu/Cu2O/ZnO/CuO metal oxides proved to be highly crystalline and showed irregularly distributed particles with different sizes. Meanwhile, Fourier transform infrared (FTIR) spectroscopy confirmed the purity while together with ultraviolet-visible (UV-Vis) spectroscopy proved the proposed mechanism of the synthesised nanocomposite. UV-Vis showed improved catalytic activity of the prepared metal oxides, evident by narrow band gap energy. The redox and electrochemical properties of the prepared nanocomposite were achieved by cyclic voltammetry (CV), electrochemical impedance (EIS) and galvanostatic charge-discharge (GCD). The maximum specific capacitance (Cs) was calculated to be 241 F g−1 at 50 mV s−1 for Cu/Cu2O/CuO/ZnO nanoplatelets structured electrode. Moreover, all the CuO nanostructures reveal better power performance, excellent rate as well as long term cycling stability. Such a study will encourages a new design for a wide spectrum of materials for smart electronic device applications.

“…Cu 2 O/ZnO solar cells have had an achievable power conversion efficiency (PCE) of >2%, where a thick Cu 2 O layer (1–3 μm) and opaque metallic electrodes (Au, Ag, or Al) − resulted in poor transparency and compromised applications. The critical factors that severely impact the PCE of solar cells are the phase purity of the Cu 2 O layer and the heterojunction interface quality that controls the generation and extraction of photogenerated carriers. , The main challenges with Cu 2 O/ZnO PV are a significant deficit in open-circuit voltage ( V OC ) and current density ( J SC ).…”

Photovoltaics (PV) would be more promising if light could generate electric power invisibly. This will endow more degrees of freedom to PV cells for wide-range deployment. Transparent photovoltaic (TPV) devices are the groundwork of the buildingintegrated photovoltaic (BIPV) systems that provide aesthetics to the buildings and solar energy convertor modules. TPV is adequate for the BIPV system of windows. Heterojunctions between p-type Cu 2 O and n-type ZnO have emerged as one of the most promising TPV devices. However, their inadequate transparency and a deficit of open-circuit voltage (V OC ) and shortcircuit current density (J SC ) remained an open challenge. In this work, we have fabricated a thin Ga 2 O 3 buffer layer embedded transparent ZnO/Cu 2 O heterojunction photovoltaic device, showing an average visible transmittance of more than 50%. The insertion of the Ga 2 O 3 buffer layer remarkably increases the J SC and V OC to ∼860% and ∼41%, respectively. The TPV device also demonstrated a high J SC of 3.41 mA/cm 2 under UV light. The Ga 2 O 3 layer provides a graded conduction band alignment and passivates the interface by the field-effect passivation mechanism. The Ga 2 O 3 buffer layer embedded device also demonstrated a broadband photodetection with remarkably high responsivity and detectivity of 250 mA/W and 5 × 10 11 Jones at self-biased conditions.
