Abstract

In a large-area photovoltaic cell containing a photoactive semiconductor layer which contacts another semiconductor layer, metal or an electrolyte to form a depletion layer, and further containing an electrode and a counter electrode for current collection, the improvement which comprises employing as a substrate for said photoactive semiconducting layer a metallized textile sheet, the metal constituting one of the electrodes, the sheet having been metallized by depositing the metal thereon wet-chemically without current. The metal thickness may be built up with or without current. Such cells have low internal resistances and are highly efficient.
