| 摘要 |
A photoelectrochemical system for the generation of hydrogen by cleavage of an electrolyte, the system comprising: an electrolyser (24) for housing an electrolyte, said electrolyser comprising first and second electrodes and being configured for collection of hydrogen liberated at one of said electrodes on operation of the system; a photoactive element (22) separated from said electrolyte and consisting of first (32) and second (34) photoactive systems electrically connected to one another in series, said first and second photoactive systems being electrically coupled to respective ones of said first and second electrodes; wherein said first photoactive system is configured to absorb and be responsive to illumination of a first range of wavelengths and at least substantially transparent to the remainder of said illumination, and said second photoactive system is configured to be responsive to illumination of a second range of wavelengths comprising at least part of the remainder transmitted by said first system. |
