Overall the manufacturing process of creating solar photovoltaics is simple in that it does not require the culmination of many complex or moving parts. Because of the solid-state nature of PV systems, they often have relatively long lifetimes, anywhere from 10 to 30 years. To increase the electrical output of a PV system, the manufacturer must simply add more photovoltaic components. Because of this, economies of scale are important for manufacturers as costs decr…
Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].
Photovoltaic (PV) devices contain semiconducting materials that convert sunlight into electrical energy. A single PV device is known as a cell, and these cells are connected together in chains to form larger units known as modules or panels. Research into cell and module design allows PV technologies to become more sophisticated, reliable, and ...
The working of solar cells is possible due to the photovoltaic effect in solar diodes as described in previous sections. The solar cell may be an a-Si cell, a monocrystalline cell, or a polycrystalline cell. When the solar light falls on the solar cell then due to the photon energy the diode current passage from a diode to the load.
