NOVELTY - Producing photovoltaic cell involves doping first surface of semiconductive substrate (1) with n-dopant (3) to form first n+ layer in the substrate; doping second surface of the substrate with p-dopant (2); removing portion of the first n+ layer from the first surface of the substrate; doping the first surface of substrate with n-dopant; and forming electrical contacts on each of the first surface and the second surface, by producing the photovoltaic cell.    USE - For producing photovoltaic cell useful in photovoltaic array and electric device, where the photovoltaic array is used in a power plant (claimed).    ADVANTAGE - The photovoltaic cell is capable of converting light directly into electricity, which provides significant source of renewable energy in the future, thus enabling a reduction in the use of non-renewable sources of energy such as fossil fuels. The strong demand for photovoltaic cells which are relatively inexpensive to produce, and has high efficiency.    DETAILED DESCRIPTION - Producing a photovoltaic cell involves doping a first surface of a semiconductive substrate (1) with an n-dopant (3) to form a first n+ layer in the substrate; doping a second surface of the substrate with a p-dopant (2) to form a p+ layer in the substrate; removing a portion of the first n+ layer from the first surface of the substrate, such that a concentration of the n-dopant remaining in the first surface of the substrate is variable throughout the first surface; doping the first surface of the substrate with an n-dopant to form a second n+ layer, such that a concentration of the n-dopant in the second n+ layer is variable throughout the first surface; and forming electrical contacts on each of the first surface and the second surface, by producing the photovoltaic cell. The p-dopant comprises boron oxide. The n-dopant comprises phosphorus pentoxide. INDEPENDENT CLAIMS are included for following:    (1) a photovoltaic cell comprising a semiconductive substrate, where substrate having n+ layer on a first surface and p+ layer on a second surface, where n+ layer comprising n-dopant and the p+ layer comprising p-dopant, and electrical contacts attached to each of the first surface and the second surface, where the first surface is textured to comprises peaks and troughs, and where the concentration of the n-dopant in the n+ layer is greater in the peaks of the first surface than in the troughs of the first surface; and    (2) a photovoltaic array comprising several of the photovoltaic cells, where several of photovoltaic cells are interconnected to one another.
