The barrier inhibits the movement of electrons from one layer to the other, so that higher energy electrons from one side diffuse preferentially through it in one direction, creating a current, and thus a voltage across the cell.  1, record 2, English, - cell%20barrier

[Pour] les piles PEMFC, l'électrolyte est une membrane polymère ionique de type acide ; dans ce type d'électrolyte, les ions négatifs sont retenus dans la structure de la membrane. Seuls les ions hydrogène H+ sont mobiles et libres de transporter la charge positive à travers la membrane, de l'anode vers la cathode et c'est ce mouvement associé à la circulation des électrons qui est à l'origine du courant produit.  6, record 3, French, - membrane%20%C3%A9changeuse%20de%20protons

There are several different types of photoelectric cells. In some [i. e., phototubes] there is a light-sensitive surface [a photocathode] which emits electrons and a second electrode, usually maintained at a fairly high positive potential, which collects the electrons... A second type is the photovoltaic or barrier layer photocell in which incident light produces an emf between two terminals... Solar cells, widely used to provide energy for satellites and space vehicles, are photovoltaic cells converting radiant energy into electrical energy. A familiar form uses a very perfect silicon crystal which is treated with trace impurities to introduce extra positive charges on one side of a thin wafer and extra negative charges on the other side... Radiant energy disturbs the electrical balance of the charges and thereby induces an emf which continues as long as light strikes the crystal... A third type of photoelectric cell [photoconductive, or photoresistive cell] utilizes the photoconductivity effect.  6, record 4, English, - photoelectric%20receptor

Dans le Dictionnaire de Physique (J.P. Mathieu, 1983), on décrit trois catégories de cellules photoélectriques, soit : 1) les cellules photoémissives (syn. : phototubes - qui ne font pas appel aux matériaux semiconducteurs); 2) les cellules photovoltaïques; 3) les cellules photoconductrices (ou photorésistantes), ces deux dernières catégories nécessitant l'emploi de semiconducteurs. Dans l'Encyclopédie internationale des sciences et des techniques on utilise le terme dans ce même sens général. Par contre, dans le Dictionnaire mémento d'électronique, Dunot, éd. Paris 1969, page 59, on exclut les phototubes. On retrouve donc, en français, la même diversité de sens des termes qu'en anglais. Cette fiche traite de ces termes dans leur sens le plus large.  1, record 4, French, - r%C3%A9cepteur%20photo%C3%A9lectrique
