PHOTOELECTROCHEMICAL REACTION DEVICE

摘要

A photoelectrochemical reaction device in an embodiment includes: first and second photovoltaic cells each including a first electrode, a second electrode, and a photovoltaic layer; first and second reaction electrode pairs each including a third electrode and a fourth electrode; and an electrolytic bath storing a first electrolytic solution in which the third electrodes are immersed and a second electrolytic solution in which the fourth electrodes are immersed. One of the third and fourth electrodes causes an oxidation reaction, and the other of the third and fourth electrodes causes a reduction reaction. The first photovoltaic cell is electrically connected to the first reaction electrode pair, and the second photovoltaic cell is electrically connected to the second reaction electrode pair.
