“…The crystallite size for all of the layers was almost the same and in the 65-73 nm range. Since the ZnO powder used was a commercially available powder, and all of the ZnO paste preparation techniques were consistent across all of the different layered photoanodes, the results demonstrate that the number of layers added has no discernible impact on the crystallite size [37,49,50].…”

Dye-sensitized solar cells (DSSCs) were developed by exploiting the photovoltaic effect to convert solar energy into electrical energy. The photoanode layer thickness significantly affects the semiconductor film’s ability to carry electronic charges, adsorb sensitizing dye molecules, and lower the recombination of photo-excited electrons injected into the semiconductor. This study investigated the dependence of the zinc oxide (ZnO) photoanode thin-film thickness and the film soaking time in N719 dye on the photocurrent–voltage characteristics. The ZnO photoanode was applied to glass using the doctor blade method. The thickness was varied by changing the scotch tape layers. The ZnO-based DSSC attained an efficiency of 2.77% with three-layered photoanodes soaked in the dye for three hours, compared to a maximum efficiency of 0.68% that was achieved with three cycles using the dip-coating method in other research. The layer thickness of the ZnO photoanode and its optimal adsorption time for the dye are important parameters that determine the efficiency of the DSSC. Therefore, this work provides important insights to further improve the performance of DSSCs.

“…Next, electrolyte that contains iodide-tri-iodide ( I − / I 3 − ) will act as the mediator to fetch the electrons which arrived at the counter electrode and regenerate the oxidized electrons in the dye molecules. The cycle will continue repeatedly with the presence of photon in the environment (Jamalullail et al, 2018). In recently years, titanium dioxide (TiO2) has attracted much attention from researchers across the globe due to its potential applications in energy generation and environmental protection and has been largely applied in DSSC due to its nanocrystalline mesoporous nature that translates to high surface area for dye absorption (Saadoun et al, 2000).…”

This article discusses the most recent developments in the manufacture of flexible dye-sensitized solar cells (DSSCs), with a focus on the use of flexible plastic substrates instead of rigid glass substrates. The temperature restriction of the substrate in generating TiO2 nanoparticles is a key problem for creating DSSCs on plastic substrates. Ball-milling, acid/water treatments, chemical vapor deposition, and electrophoretic deposition, as well as chemical and mechanical film processing methods such as chemical sintering, hydrothermal treatment, microwave irradiation, and various compression techniques, are all discussed here. It also includes research on novel flexible counter electrode manufacturing processes and recently produced new materials that are particularly beneficial for flexible DSSCs. Finally, the progress and possibilities of large-scale flexible DSSC module fabrication, as well as their endurance, are reviewed.

Ruthenium N719 is a well-known material used as the dye in commercial dye-sensitized solar cell (DSSC) devices. However, it poses risks to human health and the environment over time. On the other hand, titanium dioxide (TiO2) has low electron mobility and high recombination losses when used as a photoanode in this photovoltaic technology device. In addition, using Ruthenium as the dye material harms the environment and human health. As an alternative sensitizer to compensate Ruthenium on two different photoanodes (TiO2 and ZnO), we constructed DSSC devices in this study using three different natural dyes (blueberry, pomegranate, and black grape). In good agreement with the anthocyanin content in the fruits, black grape, with the highest anthocyanin content (450.3 mg/L) compared to other fruit dyes (blueberry—386.6 mg/L and pomegranate—450.3 mg/L), resulted in the highest energy conversion efficiency (3.63%) for the natural dye-based DSSC. Furthermore, this research proved that the electrical performance of natural dye sensitizer in DSSC applications with a ZnO photoanode is better than using hazardous Ru N719 dye with a TiO2 photoanode owing to the advantage of high electron mobility in ZnO.
