“…Moreover, the density of the donor material influences the absorption of light within the active layer. By tuning the donor density to an optimal level, the efficient absorption of photons by the photoactive materials can be ensured, thereby enhancing the generation of electron-hole pairs and subsequently increasing the photocurrent [131].…”

Among the emerging photovoltaic technologies, solid‐state dye‐sensitised solar cells (ssDSSCs) have attracted considerable interest due to their cost‐effective production, adjustable characteristics, and potential for lightweight and flexible applications. Nevertheless, achieving efficiencies comparable to established technologies, such as perovskite and silicon‐based solar devices, have proven challenging. Herein, the device structure, Pt/PEDOT: PSS/N719 dye/PC61BM/ITO is investigated theoretically using the solar cell capacitance simulator (SCAPS‐1D). Groundbreaking advancement is introduced in ssDSSC design, achieving remarkable theoretical power conversion efficiency of 20.73%, surpassing the performance reported in traditional dye‐based solar cell technologies. The model ssDSSC demonstrates an exceptional Fill factor of 86.64%, indicating efficient current collection; along with a modest short‐circuit current density (Jsc) of 22.38 mA/cm2 and an impressive open‐circuit voltage (Voc) of 1.0691 V, highlighting efficient light absorption and charge separation. Mott–Schottky capacitance analysis and parasitic resistances (series and shunt) have been thoroughly discussed. Despite the fact that only numerical simulation is involved, the proposed ssDSSCs structure gives insights into the fabrication of a highly efficient solar cell that can be injected into the production workflow in order to advance the photovoltaic technology of the solid‐state DSSC.

Solar energy, as a renewable energy source, dominates the vast majority of human energy, which can be harvested and converted by photovoltaic solar cells. However, the intermittent availability of solar energy restricts the actual utilization circumstances of solar cells. Integrating photo‐responsive electrodes into an energy storage device emerges as a dependable and executable strategy, fostering the creation of photo‐stimulated batteries that seamlessly amalgamate the process of solar energy collection, conversion, and storage in one system. Endowed by virtues such as cost‐effectiveness, facile manufacturing, safety, and environmental friendliness, photo‐stimulated Zn‐based batteries have attracted considerable attention. The progress report furnishes a brief overview, summarizing various photo‐stimulated Zn‐based batteries. Their configurations, operational principles, advancements, and the intricate engineering of photoelectrode designs are introduced, respectively. Through rigorous architectural design, photo‐stimulated Zn‐based batteries exhibit the ability to initiate charging by saving electricity usage, and in certain instances, even without the need for external electrical grids under illumination. Furthermore, the compensation of solar energy can be explored to improve the output electric energy. At last, opportunities and challenges toward photo‐stimulated Zn‐based batteries in the process of development are proposed and discussed in the hope of expanding their application scenarios and accelerating the commercialization progress.
