We used the light absorbing liquid with selectivity as the medium to adjust the light and realize the conversion of heat and light.

采用选择性吸光液体作为调光及光热转换介质。

If the energy of these hot electrons could be captured before it is converted into wasted heat, solar-to-electric power-conversion efficiencies could be increased to as high as 66%, say scientists.

科学家们称，如果这些热电子能够在转化成热能浪费掉之前被捕获，光电能量转化可以达到最高66%的效率。

The major difference between these two power generators is that the chemical energy of the fuel cell is converted directly to electrical power without intermediate conversion first to heat.

主要的区别在于，燃料电池的化学能量能直接转化成电能而不需要先转化成热能。

Secondly, when considering end-to-end efficiency, it is much less energy-intensive to heat water by direct use of natural gas on-site, rather than by using that natural gas to first make electricity that is used to heat water because of the large conversion losses at power plants.
