“…However, for large-area devices, excessive film thickness may introduce defects and organic material aggregation, resulting in a decrease in the fill factor. Therefore, the optimization of the morphology and film thickness of the active layer is necessary to improve the fill factor [27][28][29][30][31]. Additionally, thin-film annealing is a crucial thermal treatment process that significantly impacts the film quality [32][33][34][35].…”

This research focuses on the fabrication and optimization of large-area PM6:D18-CL:Y6 ternary organic solar cells, with a particular emphasis on film thickness, annealing temperature, and the connection configuration’s impact on device performance. The experimental findings indicate that an optimal film thickness of approximately 105 nm fosters the formation of a well-interconnected network, reducing defects and significantly improving both the fill factor, which reaches 46.2%, and the power conversion efficiency (PCE) at 7.2%. An annealing temperature of 110 °C stands out as the ideal condition, resulting in the highest PCE of 8.15%. Notably, excessively high annealing temperatures lead to material aggregation, compromising device performance. Regarding the connection configurations, the study demonstrates that the 5-series 4-parallel arrangement surpasses traditional setups, achieving an impressive output power of 0.11 W. In conclusion, the meticulous control of the film thickness and annealing temperature is paramount for achieving a high PCE in large-area PM6:D18-CL:Y6 ternary organic solar cells. The 5-series 4-parallel configuration exhibits considerable promise for an enhanced power output, offering valuable insights into the development and industrialization of large-area organic solar cells.

“…Though the power conversion efficiency (PCE) of OSCs has been found to be over 17% [4], further improvement in performance has encountered a bottleneck due to the limited understanding towards how these dynamic processes determine the performance of OSCs. To explore this issue, some experimental methods have been developed, such as inserting a buffer layer [5,6], tailoring the thin film morphology [7,8], optimizing the active layer deposition [9], or designing annealing methods [10]. Among these methods, temperature control has been regarded as one of the most important approaches thanks to its significant impact on the performance of OSCs [11,12].…”

Influence of Temperature on Exciton Dynamic Processes in CuPc/C60 Based Solar Cells

Although the effect of high temperature on the performance of organic solar cells has been widely investigated, it is inevitably influenced by the associated annealing effect (which usually leads to film morphology change and variation in electrical properties), which makes the discussion more sophisticated. In this study, we simplified the issue and investigated the influence of low temperatures (from room temperature to 77 K) on the photocurrent and internal/external quantum efficiency of a CuPc/C60 based solar cell. We found that besides the charge dynamic process (charge transport), one or more of the exciton dynamic processes, such as exciton diffusion and exciton dissociation, also play a significant role in affecting the photocurrent of organic solar cells at different temperatures. Additionally, the results showed that the temperature had negligible influence on the absorption of the CuPc film as well as the exciton generation process, but obviously influenced the other two exciton dynamic processes (exciton diffusion and exciton dissociation).
