To investigate the photovoltaic capabilities as a sensitizer and co-sensitizer for dye-sensitized solar cells (DSSCs), a new metal-free organic dye (CDIB) was synthesized. In addition, different concentrations of 1-n-hexyl-3-methylimidazolium iodide ionic liquid (IL) doped poly(vinylidene fluoride-hexafluoropropylene) gel polymer electrolytes are prepared and the high conductive electrolyte is used to fabricate the devices. The device having CDIB sensitizer and IL-15% electrolyte showed an efficiency of 1.86%. Further, the effect of CDIB co-sensitization on Z907 is examined. Consequently, the power conversion efficiency of DSSC with co-sensitized dye is raised by 23.29%, from 4.55 to 5.61%, when compared to DSSCs with individual dyes. This improvement is mostly due to an increase in a short-circuit current density and open-circuit voltage. Highlights• Co-sensitization is being used to enhance the performance of DSSCs.• Poly(vinylidene fluoride-hexafluoropropylene)-based gel polymer electrolytes doped with different amounts of 1-n-hexyl-3-methylimidazolium iodide were prepared for improving the conductivity of electrolyte.• A co-sensitized DSSC has an efficiency of 5.61%.• With co-sensitization, both V OC and J SC increased significantly.

“…However, research on flexible photovoltaic cells is increasingly reported in the literature. The most common flexible substrates used in photovoltaics are made of polymers such as polyethylene naphthalate (PEN) or polyethylene terephthalate (PET) [ 22 , 23 , 25 , 26 , 27 , 28 , 29 ]. Subsequently, polymers are used as materials responsible for forming the porous structure of a semiconducting oxide layer, e.g., TiO 2 .…”

Third-generation solar cells, including dye-sensitized solar cells, bulk-heterojunction solar cells, and perovskite solar cells, are being intensively researched to obtain high efficiencies in converting solar energy into electricity. However, it is also important to note their stability over time and the devices’ thermal or operating temperature range. Today’s widely used polymeric materials are also used at various stages of the preparation of the complete device—it is worth mentioning that in dye-sensitized solar cells, suitable polymers can be used as flexible substrates counter-electrodes, gel electrolytes, and even dyes. In the case of bulk-heterojunction solar cells, they are used primarily as donor materials; however, there are reports in the literature of their use as acceptors. In perovskite devices, they are used as additives to improve the morphology of the perovskite, mainly as hole transport materials and also as additives to electron transport layers. Polymers, thanks to their numerous advantages, such as the possibility of practically any modification of their chemical structure and thus their physical and chemical properties, are increasingly used in devices that convert solar radiation into electrical energy, which is presented in this paper.

Solar energy as one of the main renewable energy sources displays the key way to become a critical element for production of future global energy. A high share of variable renewable energy sources in the electricity mix reduces security and flexibility of supply, making it challenging to balance the market at all times. To solve the mismatch between the seasonal and daily patterns of demand and supply, energy storage has been used. Today, hydrostorage is the most used energy storage technology. Therefore, the study is about designing of nano-structured coatings that are decorated by thermodiffusion and polymerization methods for solar-hydro electricity generation. For achieving this purpose, lead titanate (PbTiO 3 ) and copper phthalocyanine (CuPc) nanostructures are prepared by simple sol-gel process. Then, the nanostructures are coated on the surface of selected electrodes via thermodiffusion and polymerization methods. Various techniques containing Fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and cyclic voltammetry (CV) are used for characterization and study of the nanostructures. After characterization of the nanostructures, the electrical characteristics of the coatings are investigated via an electrochemical technique. Voltammetry analysis shows that electrically conductive nanolayers are formed and therefore, the photovoltaic performance of them is investigated. The results indicate that the thermodiffusion and polymerization methods present novel, operative, and simple approaches for the electron transport that increases photocurrent and thus, power conversion efficiency for solar-hydro electricity generation.
