Photoelectrochemical processes use specialised semiconductors to separate water into hydrogen and oxygen. Photo voltaic thermochemical hydrogen output uses concentrated solar power to travel water splitting reactions frequently along with other species including metal oxides. On the other side of the controller, two LEDs are delivered for self-diagnostic and repair purposes. https://reidpqoli.wikipowell.com/5414760/not_known_facts_about_bis_30_sprit_sparen
