ABSTRACT:
Solar cells having a semiconductor body composed of amorphous silicon which is applied to a substrate coated at least at one surface thereof with aluminum, functioning as a back contact. Recrystallization is prevented by alloying silicon or silicon/titanium into the aluminum layer so that the amounts of silicon within the alloy is, in preferred embodiments, about 1.3% by weight and, with the presence of 0.1% by weight titanium, is at about 1.2% by weight.
