The present invention provides a photovoltaic cell comprising (a) a cadmium telluride film (3), (b) a barrier layer (5) facing and in intimate contact with one side of said film with a rectifying junction at the interface therebetween and (c) a conductive layer (6) facing and in intimate contact with the other side of said film with an ohmic junction at the interface therebetween, wherein the film is relatively cadmium-rich at the ohmic junction interface. …<??>The present invention also provides a method of making a photovoltaic cell, wherein cadmium telluride is electrodeposited on a smooth cadmium surface, a photovoltaic cadmium telluride film thereby being formed and ohmic contact being made between the cadmium telluride film and the cadmium surface substrate. |
