INTERCONNECTED PHOTOELECTROCHEMICAL CELL

摘要

An interconnected photoelectrochemical (PEC) cell (1) generates hydrogen and oxygen from water while being illuminated with radiation such as sunlight. The photovoltaic structure in the photoelectrode is deposited on a transparent and insulating substrate (also called superstrate) (3) that is covered with a transparent conducting layer (front electrode) (4). The front electrode is electrically connected to the back side of the photovoltaic structure such that the PEC cell can be made with high efficiency and high durability and at low cost. Three types of photoelectrodes and phtoelectrochemical cells are illustrated as examples.
