Transparent conducting electrodes (TCEs) are integral components in optoelectronic devices, facilitating both light transmission and electrical conduction. Over the past four decades, substantial advancements have been made in TCE materials, including transparent conducting oxides (TCOs) such as indium tin oxide (ITO) and fluorine‐doped tin oxide (FTO), which remain dominant technologies in practical applications. Despite these advancements, current TCEs exhibit relatively high sheet resistance (Rsheet), posing a significant barrier to the scale‐up of solution‐processed devices such as organic photovoltaics (OPVs). This work addresses the scaling limitations of TCEs in OPVs by proposing the integration of a TCE with a metallic grid (g‐TCE) to mitigate the high Rsheet issue. The performance of g‐TCEs in OPVs is evaluated across various irradiance levels and TCE Rsheet values. Additionally, a novel, unitless figure‐of‐merit tailored to specific PV devices is introduced, which enables benchmarking beyond traditional TCE FoMs. Exemplifications of g‐TCEs include aluminium‐doped zinc oxide (AZO), which has an equivalent Rsheet of 0.5 Ω □−1, while maintaining an average visible transmittance exceeding 77%, outperforming all state‐of‐the‐art monolithic TCE materials. These findings demonstrate that g‐TCEs present a viable pathway for the development of large‐area, solution‐processed PV devices.

应用：用于有机光伏的靶向金属网格增强透明电极


透明导电电极 （TCE） 是光电器件中不可或缺的元件，可促进光传输和导电。在过去的四十年中，TCE 材料取得了重大进步，包括透明导电氧化物 （TCO），如铟锡氧化物 （ITO） 和氟掺杂氧化锡 （FTO），这些材料在实际应用中仍然是主导技术。尽管取得了这些进步，但目前的 TCE 仍表现出相对较高的薄层电阻 （Rsheet），对有机光伏 （OPV） 等溶液处理器件的放大生产构成了重大障碍。这项工作通过提出将 TCE 与金属网格 （g-TCE） 集成以缓解高 Rsheet 问题，解决了 OPV 中 TCE 的扩展限制。在各种辐照度水平和 TCE Rsheet 值下评估 OPV 中 g-TCE 的性能。此外，还引入了一种针对特定 PV 器件量身定制的新颖、无单位品质因数，这使得基准测试能够超越传统的 TCE FoM。g-TCE 的示例包括掺铝氧化锌 （AZO），其等效 Rsheet 为 0.5 Ω □−1，同时保持超过 77% 的平均可见透射率，优于所有最先进的整体 TCE 材料。这些发现表明，g-TCEs 为开发大面积、溶液处理的 PV 器件提供了一种可行的途径。
