Photovoltaic (PV) cells, commonly known as solar cells, are the building blocks of solar panels that convert sunlight directly into electricity. Understanding the construction and working principles of PV cells is essential for appreciating how solar energy systems harness renewable energy.
Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
The working principle of a photovoltaic (PV) cell involves the conversion of sunlight into electricity through the photovoltaic effect. Here's how it works: Absorption of Sunlight: When sunlight (which consists of photons) strikes the surface of the PV cell, it penetrates into the semiconductor material (usually silicon) of the cell.
Understanding the construction and working principles of PV cells is crucial for appreciating how solar energy is harnessed to generate electricity. The photovoltaic effect, driven by the interaction of sunlight with semiconductor materials, enables the conversion of light into electrical energy.
The document discusses photovoltaic or solar cells. It defines solar cells as semiconductor devices that convert light into electrical energy. The construction of a basic silicon solar cell is described, involving a p-type and n-type semiconductor material forming a PN junction.
