“…Figure 3c shows the TiO 2 -ZrO 2 film has uniform surface area than the pristine ZrO 2 and TiO 2 which leads to better dye adsorption and results in enhancing the overall performance of the DSSC for TiO 2 -ZrO 2 bilayered photoanode. The layer-by-layer structure of TiO 2 -ZrO 2 bilayered photoanode exhibit moderate surface area compared with the pristine bulk materials positive sign for amount of dye adsorption and also leads to the shortened collection length for charges results into increasing efficiency [41]. The values of surface area measure by BET technique for all the samples are summarized in Table 2 and found to be in accordance with the previously reported results [42].…”

TiO 2 , ZrO 2 and layer-by-layer TiO 2-ZrO 2 films were prepared by doctor blade method followed by sensitization with natural dye for dye-sensitized solar cell application. The structural and optical, morphological and compositional properties were investigated by X-ray diffraction and UV-Vis spectroscopy, scanning electron microscopy, BET, surface profilometer and energy-dispersive X-ray analyzer, respectively. Dye-sensitized solar cells were fabricated using the prepared electrodes of TiO 2 , ZrO 2 and layer-by-layer TiO 2-ZrO 2 films sensitized with natural dye extracted from Pandan leaves (Pandanus amaryllifolius). The J-V characteristics were recorded to measure photo-response of fabricated devices and electrochemical impedance spectroscopy to study the electron behavior, series resistance and lifetime. Photovoltaic parameter like shortcircuit current, open-circuit voltage, fill factor, and power conversion efficiency were evaluated for fabricated solar cell under artificial light supplied from white LED (15 mW·cm −2). The average values of power conversion efficiency of DSSCs fabricated with TiO 2 , ZrO 2 and layer-by-layer TiO 2-ZrO 2 photoanodes were found to be 0.65%, 3.04% and 3.13%, respectively.

This study reports the performance of simple low-cost synthesized bifunctional Cu/Cu2O nanoparticles (NPs) used as a catalyst for energy-harvesting applications through of a microfluidic fuel cell (µFC), and further, as cholesterol (Chol) sensor. TEM characterization of the NPs showed spheres between 4 and 10 nm, while XRD and XPS analysis confirmed the composition and preferential crystallographic plane of Cu/Cu2O. In addition, 25.26 m2 g−1 surface area was obtained, which is greater than those commercial materials. NPs showed high activity toward the cholesterol oxidation reaction when were used as a sensor, obtaining a linear interval between 0.5 and 1 mM and 850 µA mM−1 mg−1 of sensitivity and 8.9 µM limit of quantification LOQ. These values are comparable to results previously reported. Moreover, Cu/Cu2O NPs were used as anode in a µFC with 0.96 V of cell voltage and 6.5 mA cm−2 and 1.03 mW cm−2 of current and power density, respectively. This performance is the highest currently reported for cholesterol application as an alternative fuel, and the first one reported for a microfluidic fuel cell system as far as is known. Results showed that the obtained Cu-based NPs presented an excellent performance for the dual application both µFC and sensor, which has potential applications in biomedicine and as an alternative energy source.

Role of a Solution-Processed V₂O₅ Hole Extracting Layer on the Performance of CuO-ZnO-Based Solar Cells

In this research, a heterostructure of the CuO-ZnO-based solar cells has been fabricated using low-cost, earth-abundant, non-toxic metal oxides by a low-cost, low-temperature spin coating technique. The device based on CuO-ZnO without a hole transport layer (HTL) suffers from poor power conversion efficiency due to carrier recombination on the surface of CuO and bad ohmic contact between the metal electrode and the CuO absorber layer. The main focus of this research is to minimize the mentioned shortcomings by a novel idea of introducing a solution-processed vanadium pentoxide (V 2 O 5 ) HTL in the heterostructure of the CuO-ZnO-based solar cells. A simple and low-cost spin coating technique has been investigated to deposit V 2 O 5 onto the absorber layer of the solar cell. The influence of the V 2 O 5 HTL on the performance of CuO-ZnO-based solar cells has been investigated. The photovoltaic parameters of the CuO-ZnO-based solar cells were dramatically enhanced after insertion of the V 2 O 5 HTL. V 2 O 5 was found to enhance the open-circuit voltage of the CuO-ZnO-based solar cells up to 231 mV. A detailed study on the effect of defect properties of the CuO absorber layer on the device performance was theoretically accomplished to provide future guidelines for the performance enhancement of the CuO-ZnO-based solar cells. The experimental results indicate that solution-processed V 2 O 5 could be a promising HTL for the low-cost, environment-friendly CuO-ZnO-based solar cells.
