“…Due to difficulty in n‐type doping, most of the copper oxide‐based solar cells are heterojunction based rather than homojunction . Currently, there are reports of solar cells based on Cu 2 O reaching more than 5% power conversion efficiency and CuO reporting PCE value of <1.5% . Most of these solar cells are fabricated using highly energy consuming annealing methods or in the dye sensitised solar cell structure with unstable electrolyte.…”

p‐type copper oxide (CuO) nanocrystals were prepared by a wet chemical method and are used to make thin films by spin casting. CuO nanocrystals were characterised using XRD, Raman, TEM and XPS. Low temperature solution processed thin films of CuO crystals showed a hole mobility of 4.57 × 10−4 cm2 V−1 s−1 perpendicular to the plane of the film and is measured using space charge limited current method. Due to the difficulty in making solution processed homo p–n junction and n‐doping of CuO, a planar hybrid heterojunction solar cell is fabricated using solution processed CuO and a n‐type organic material, [6,6]‐phenyl‐C70 butyric acid methyl ester (PCBM). A power conversion efficiency of 0.23% is obtained for hybrid solar cell comprising CuO as active layer where all the device fabrications were carried out at temperature ≤100 °C. Analysis of the current density–voltage (J–V) characteristics at different light intensities is carried out to unravel the recombination mechanism occurring at the interface. Further, effect of annealing the active layer on the photovoltaic performance is investigated.

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.

Sun energy conversion to electrical energy using nanostructured organic/inorganic hybrid semiconductors is one of the best solutions for today's energy crisis. In particular, researchers are focusing on multitechniques to increase the power conversion efficiency of polymer solar cells, including thermal annealing and the incorporation of metal or transition metal oxide nanoparticles (NPs) into the active layer of polymer solar cells (PSCs). The design approaches for thermal annealing are to improve the nanoscale morphology and optical properties of the active layer. The incorporation of metal NPs is based on localized surface plasmonic resonance (LSPR) effect which can be used to enhance the optical absorption in photovoltaic devices. Meanwhile, transition metal oxide NPs such as copper oxide (CuO) NPs in the active layer play a key role as light harvesting centers, charged particle hopping centers, and surface morphology developer, enabling a considerable reduction in the physical thickness of solar photovoltaic absorber layers. In this study, thermal annealing was used to optimize the power conversion efficiency of bulk heterojunction P3HT/PC70BM SCs synthesized by incorporating gold nanoparticles and copper oxide nanoparticles. Thermal annealing increased the power conversion efficiency by up to 48.3 % compared to the reference cell. The optimum short-circuit current (Jsc) of the cells was measured to be 8.704 mA/cm 2 compared to 5.838 mA/cm 2 in the reference cell; meanwhile, the external quantum efficiency (EQE) increased from 44 to 64 %.
