Abstract This work is concerned with the utilization of silver doped reduced graphene oxide (Ag-rGO) films as counter electrode in a dye-sensitized solar cell (DSSC). The effect of annealing temperature of Ag-rGO on the properties of Ag-rGO and performance parameters of the device has been investigated. The annealing temperature has been varied from 350 °C to 400 °C at 10 °C interval. The DSSC utilizing Ag-rGO annealed at 350 °C demonstrated the highest η of 1.302%, respectively due to the smallest charge transfer resistance at the interface of electrolyte/Ag-rGO counter electrode. The efficiency has been improved by utilizing the Ag-rGO counter electrode that underwent annealing treatment. The performance and electrochemical stability test reveal that the DSSC utilizing free-platinum electrode that is Ag-rGO can last within one week time.

利用掺银还原氧化石墨烯薄膜对电极的染料敏化太阳能电池：退火温度对其性能的影响

摘要 这项工作涉及利用掺银还原氧化石墨烯 (Ag-rGO) 薄膜作为染料敏化太阳能电池 (DSSC) 中的对电极。研究了 Ag-rGO 的退火温度对 Ag-rGO 性能和器件性能参数的影响。退火温度以 10°C 的间隔从 350°C 变化到 400°C。由于电解质/Ag-rGO 对电极界面处的电荷转移电阻最小，使用在 350°C 下退火的 Ag-rGO 的 DSSC 分别表现出 1.302% 的最高 η。通过使用经过退火处理的 Ag-rGO 对电极，效率得到了提高。性能和电化学稳定性测试表明，使用游离铂电极 Ag-rGO 的 DSSC 可以持续一周。
