Silicon wafers undergo processing into photovoltaic cells through foundational steps including cleaning, cutting, etching, diffusion, and deposition. The creation of a solar pn junction primarily involves fundamental processes that combine semiconductor materials to facilitate the conversion of sunlight into electricity. Fundamental materials involved include silicon, a commonly used semiconductor; 2. While some concentrating solar-thermal manufacturing exists, most solar manufacturing in the United States is related to photovoltaic (PV) systems. EVA A copolymer of ethylene and vinyl. We describe an upper-division undergraduate physics laboratory experiment that integrates the fabrication and characterization of a p-n junction in silicon. Under standard illumination, this p-n junction exhibits the photovoltaic effect as well as the typical diode rectification behavior when. While photovoltaic effect readily takes place in a number of materials, the third step - separation of the charge carriers - is probably the trickiest from the technical point of view.
