Wenn sie jetzt hier bei 1,3 oder 1,5V wären oder andere Materialien vorweisen könnten, dann würde es anders aussehen
Auszug aus der PR v. 09.12.2014:
" The theoretical minimum voltage needed to split water molecules into hydrogen and oxygen is 1.23 V. However, in real world systems, 1.5 V or more is generally needed because of the low reaction kinetics. So far, other researchers have only been able to achieve this voltage level through the use of either inefficient materials, such as titanium oxide, or very expensive semiconductors, such as gallium arsenide. Also, overcoming the corrosive degradation of these "artificial photosynthesis" systems remains a monumental challenge and has thus far eluded commercialization.
HyperSolar has previously solved the degradation problem through the use of its patent-pending protective coating, which has demonstrated long stability. Now, with 1.25 V of water splitting voltage through an inexpensive but efficient solar absorber, the company has achieved something that has never been done in a real-world environment. Future development efforts will focus on increasing the currents and photovoltages beyond 1.5V."
