Cost-effective, parallel grids embedded dye-sensitized solar mini-modules were fabricated successfully by utilizing reduced graphene oxide (rGO) and rGO-silver (rGO-Ag) nanocomposites as grid current collectors. The pure rGO grids embedded dye-sensitized solar mini-module showed a maximum power conversion efficiency of 4.10% with improved fill factor, circumvented iodide/triiodide electrolyte corrosion, and reduced the module power loss significantly. Electrochemical impedance spectroscopy studies revealed that the 1:1 wt% ratio rGO-Ag nanocomposite grids improved the module's electron diffusion length, carrier mobility and lifetime, and produced a higher open-circuit voltage (Voc) as compared with the pure silver grids in the dye-sensitized solar mini-module.

制造具有成本效益的还原氧化石墨烯基平行网格嵌入染料敏化太阳能微型模块

通过使用还原氧化石墨烯 (rGO) 和 rGO-银 (rGO-Ag) 纳米复合材料作为网格集电器，成功地制造了具有成本效益的平行网格嵌入染料敏化太阳能微型模块。纯 rGO 网格嵌入染料敏化太阳能微型组件的最大功率转换效率为 4.10%，填充因子得到改善，避免了碘化物/三碘化物电解质腐蚀，并显着降低了组件功率损失。电化学阻抗谱研究表明，与纯银网格相比，1:1 wt% 的 rGO-Ag 纳米复合网格提高了模块的电子扩散长度、载流子迁移率和寿命，并产生了更高的开路电压 (Voc)。染料敏化太阳能微型组件。
