光电化学(PEC)制氢中太阳能转换效率的评价方式之比较

Assessment Formats for Estimating Solar-energy-conversion-efficient in Photoelectrochemical H_2 Generation

相对于人口的迅猛发展,能源危机日趋严重.太阳能光电化学(PEC)水解制氢是开发利用新能源的一个选项,是将太阳能直接转换成化学能领域中的研究热点之一.这里,系统归纳了文献中出现的关于PEC水解制氢过程中太阳能转换效率的评价方式,并加以对比,阐述了其中的优缺点,提出了如何恰当地选择评价参数以求能更好地估算PEC水解制氢过程中太阳能转换效率的建议.这项工作将为太阳能到化学能的转化和利用研究提供有益帮助.

Energy crisis is on the rise facing the population explosion around the whole world.Photoelectrochemical（ PEC） water splitting for H）_2 generation is a promising talent for exploring new types of energy supply. And it is also one of the most cutting-edge technologies in the field of conversion and application from solar to chemical energy. Here we studied and compared the advantages and disadvantages of the reported assessment approaches which evaluating the solar energy coversion efficiency in PEC H）_2 generation. Some suggestions were presented here about which parameters should be chosen to estimating the solar energy coversion efficiency more precisely. This work would do some favor in the researching of solar-to-chemical energy conversion and application.
