The efficiency of such a solar cell would depend on the materials used for the electrode, according to the researchers.

研究人员指出，以此机制为基础的太阳能电池的效率将取决于电极材料的使用。

So far, manufacturers have not established a universal labeling system to indicate the production materials and efficiency of every product.

截至目前，制造商并未对每种产品都建立起标志其所用材料和运行效能的通用体系。

But the NREL team is confident they can squeeze more efficiency out of them, and that the process can be done with readily available industrial materials and equipment.

然而NREL团队的科学家对此很有信心，相信通过可供利用的工业材料与设备能够提高这种电池的效率。
