和现在运用在太阳能板的光电伏打科技不同，新的方法在温度越高的时候表现越好，光能伏打方法在温度升高时则效率逐渐降低。
Unlike photovoltaic technology currently used in solar panels — which becomes less efficient as the temperature rises — the new process excels at higher temperatures.
我们描述的是一个新的物理过程。并非基于标准的光电伏打机理，但是你可以想象成是一个能在非常高的温度下进行的光电伏打反应。
"What we've demonstrated is a new physical process that is not based on standard photovoltaic mechanisms, but can give you a photovoltaic-like response at very high temperatures," Melosh said.
然而，在热清洗过程中对处在真空系统中的光电阴极表面温度进行精确测量却是非常困难的。
It is very difficult to measure precisely the surface temperature of a photocathode in a vacuum system during the thermal cleaning.
