巴德表示，经过这样的转换，在人工混合紫外线与可见光下的效率最多可提高到两倍。
This shift as much as doubles the efficiency under an artificial mixture of ultraviolet and visible light, Bard says.
科学家模拟太空环境，首先将混合物降温，直到接近绝对零度后，以强烈的紫外线照射混合物。
The scientists mimicked a space environment by freezing the mixture to temperatures close to absolute zero, then exposing it to harsh ultraviolet radiation.
