“…Sufficient light absorption is achieved by the nanocrystalline form of the semiconductor, because a large internal surface area increases the dye concentration in the film per unit device area. Wide band gap MOSs ( > 3 eV) [57], such as TiO 2 [58][59][60], ZnO [61][62][63][64][65][66][67], SnO 2 [60,[68][69][70][71], and Nb 2 O 5 [72][73][74], have been studied more or less extensively and used as photoanode materials for DSSC devices. These MOSs present good stability against photocorrosion, transparency in the major part of the solar spectrum, and good electronic properties [75][76][77][78].…”

Since O’Regan and Grätzel’s first report in 1991, dye-sensitized solar cells (DSSCs) appeared immediately as a promising low-cost photovoltaic technology. In fact, though being far less efficient than conventional silicon-based photovoltaics (being the maximum, lab scale prototype reported efficiency around 13%), the simple design of the device and the absence of the strict and expensive manufacturing processes needed for conventional photovoltaics make them attractive in small-power applications especially in low-light conditions, where they outperform their silicon counterparts. Nanomaterials are at the very heart of DSSC, as the success of its design is due to the use of nanostructures at both the anode and the cathode. In this review, we present the state of the art for bothn-type andp-type semiconductors used in the photoelectrodes of DSSCs, showing the evolution of the materials during the 25 years of history of this kind of devices. In the case ofp-type semiconductors, also some other energy conversion applications are touched upon.

This research is centered on the investigation of a dye‐sensitized solar cell (DSSC) with a particular focus on the utilization of anthocyanin as a sensitizing agent, in conjunction with zinc oxide (ZnO) and lithium‐doped ZnO aggregates. A notable feature of this study is its emphasis on employing cost‐effective materials in the fabrication process, aligning with the quest for sustainable and economically viable solar cell technologies. This study explores a DSSC, specifically employing anthocyanin as a sensitizer, along with ZnO and lithium‐doped ZnO aggregates. The fabrication utilizes cost‐effective materials. The research delves into morphological studies of both ZnO and its doped counterpart. Fourier transform infrared spectra were recorded for both crude and purified dyes extracted from purple cabbage. The current density–voltage profile highlights superior power conversion efficiency in the DSSC using purified dye from purple cabbage sensitized with lithium‐doped ZnO semiconductor. Overall, these experimental findings underscore the potential of anthocyanin pigments for efficient energy conversion within the realm of renewable energy technologies. By employing low‐cost materials and thoroughly investigating the morphological and spectroscopic properties of the involved components, this research contributes to the ongoing efforts in advancing clean and sustainable solar cell technologies, thereby paving the achievement of environmental sustainability.
