What are photovoltaic solar cells?


Question:


Answer:
They are solar cells that convert sunlight into voltage.
photovoltaic solar cells are some device that when sun shines on them they can generate electricity!! they work as a small battery ! they produce 0.5 volt and about 40 mA for each cm^2
any device that directly converts the energy in light into electrical energy through the photovoltaic effect. The overwhelming majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous (noncrystalline) to polycrystalline to crystalline (single crystal) silicon forms. Unlike batteries or fuel cells, solar cells do not utilize chemical reactions or require fuel to produce electric power, and, unlike electric generators, they do not have any moving parts.
