“…The sample shows the suitability of CuO thin films as an absorber layer in photovoltaic devices. Our results are in agreement with the data obtained by various methods for CuO powder, films and hybrid devices as reported in literature [3,[18][19][20][21][22][23][24]. Figure 10 shows the variations of bandgap with different types of EDTA concentration.…”

Copper oxide is a compound that has been considered significant owing to its many advantages such as easy availability of copper in huge quantity, its non-toxic nature and the good electrical and optical properties. It is p-type with bandgap range of 1.21-1.51 eV and has potential of absorption of solar spectrum. In this work, sol-gel chemistry is explored to deposit CuO using cupric chloride dihydrate (CuCl 2 · 2H 2 O) with 5, 10 and 15% concentration of EDTA (capping agent) using low-cost dip-coating and annealed at 400°C. The bandgap of the CuO films was found to be in the range of 1.3-1.8 eV, which is comparable with the reported values and also suggests quantum shift in these nanostructures. These investigations suggest suitability of these layers as absorber for photovoltaic applications. SEM investigation suggests the uniform growth of layers by dip-coating techniques. Capping also appears to control the grain growth as observed by electron microscopy. Sol-gel dipcoating technique is presented in this study for deposition of flat layers. ★ Contribution to the topical issue "Materials for Energy harvesting, conversion and storage (Icome 2017)", edited

“…The result was explained taking into account that the addition of CuO leads to a better absorption of the active layer, an increase of the exciton diffusion coefficient due to high hole and electron mobility, an increase of the exciton dissociation, and a better pathway in the composite blend for the charge transport process. prepared and evaluated cell structures with active layers based on ternary blends containing P3HT:CuO:PCBM [181]. Similar with the other studies, the optimum CuO amount required for improving the cell efficiency was found by varying the ratio between P3HT and CuO nanoparticles within the active layer.…”

Continuing growth in global energy consumption and the growing concerns regarding climate change and environmental pollution are the strongest drivers of renewable energy deployment. Solar energy is the most abundant and cleanest renewable energy source available. Nowadays, photovoltaic technologies can be regarded as viable pathways to provide sustainable energy generation, the achievement attained in designing nanomaterials with tunable properties and the progress made in the production processes having a major impact in their development. Solar cells involving hybrid nanocomposite layers have, lately, received extensive research attention due to the possibility to combine the advantages derived from the properties of both components: flexibility and processability from the organic part and stability and optoelectronics features from the inorganic part. Thus, this review provides a synopsis on hybrid solar cells developed in the last decade which involve composite layers deposited by spin-coating, the most used deposition method, and matrix-assisted pulsed laser evaporation, a relatively new deposition technique. The overview is focused on the hybrid nanocomposite films that can use conducting polymers and metal phthalocyanines as p-type materials, fullerene derivatives and non-fullerene compounds as n-type materials, and semiconductor nanostructures based on metal oxide, chalcogenides, and silicon. A survey regarding the influence of various factors on the hybrid solar cell efficiency is given in order to identify new strategies for enhancing the device performance in the upcoming years.

“…Low-dimensional CuO structures (nanorods and nanofibers) are being used in hybrid and DSSC-dye-sensitized solar cells [16,17]. Recently, our group reported CuO nanoparticles (≤ 50 nm) employed in the polymer-active layer using inverted architecture to increase light absorption range, thereby improving the PCE of devices doped with CuO nanoparticles [18]. Furthermore, ZnO nanoparticles (≤ 100 nm) had been added in the (P3HT + PCBM) active layer of the hybrid organic solar cell to increase the electron mobility in the active layer leading to a remarkable increase in PCE as compared to devices without nanoparticles [19].…”

In this work, heterojunction, solar cells based on inorganic semiconductors were fabricated at various thermal-annealing temperatures using vapor deposition techniques. The active layer primarily consists of a bilayer comprising a hole transporting copper oxide-CuO and an electron transporting zinc oxide-ZnO nanoparticles. It was observed that the power conversion efficiency-PCE increased from 0.06 to 0.08% with an increase in annealing temperature from 400 to 500 °C, possibly, as a result of increased absorption, in the visible region with increasing temperature. A significant increase in the crystallinity of single and bilayer films was also observed with increasing annealing temperature.
