The cavity can effectively choose center frequency, increase electron efficiency and output power of the Raman FEL operating in quasi -single mode regime.

该腔既可有效地选定中心频率，又可望提高准单模运转的喇曼自由电子激光器电子效率及其输出功率。

The team will now attempt to detect the transferred electrons as current and make solar cells that exploit hot electron transfer, even if the efficiency is still low.

该团队将尝试探测电子传导的电流并制作基于热电子传导的太阳能电池板，即使其能量转化效率仍然很低。

However, if such high-efficiency solar cells based on hot-electron transfer are to be become a reality, we have shown the necessary first step.

不过，如果基于热电子传导的高效太阳能电池板最终能实现的话，我们已经踏出了所必须的第一步。
