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。

The coefficient ofheatconversion from plastic work to heat can be indirectly measured.
