Two other types of PV cells that do not rely on the PN junction are dye-sensitized solar cells and organic photovoltaic cell. PV technology is a rapidly growing field and many improvements, especially in efficiency and cost, can be expected. Photovoltaic cells are made from a variety of semiconductor materials that vary in performance and cost.
The three main types of photovoltaic (PV) cell include two types of crystalline semiconductors (Monocrystalline, Polycrystalline) and amorphous silicon thin film. These three types account for the most market share. Two other types of PV cells that do not rely on the PN junction are dye-sensitized solar cells and organic photovoltaic cell.
The key feature of conventional Photovoltaic PV (solar) cells is the PN junction. In the PN junction solar cell, sunlight provides sufficient energy to the free electrons in the n region to allow them to cross the depletion region and combine with holes in the p region. This energy creates a potential difference (voltage) across the cell.
Photovoltaic solar panels are made up of different types of solar cells, which are the elements that generate electricity from solar energy. The main types of photovoltaic cells are the following: Monocrystalline silicon solar cells (M-Si) are made of a single silicon crystal with a uniform structure that is highly efficient.
The majority of PV cells, including those discussed above, contain only one p-n junction of semiconductor material which converts energy from one discreet portion of the solar spectrum into useful electricity.
Basically, there are three main categories of conventional solar cells: monocrystalline semiconductor, the polycrystalline semiconductor, an amorphous silicon thin-film semiconductor. The crystallinity of a material indicates how perfectly ordered the atoms are in the crystal structure.

While solar cells are made with a large area PN junction, a LED has only a small surface area in comparison. We can show the photovoltaic effect by wiring 10 LED''s in parallel. When exposed to sunlight, the LED''s will clearly generate electric current. See photograph. The ten LED''s will not generate as much electric power as a solar cell, but it does demonstrate the photovoltaic …
The sub-cells in multi-junction solar cells are connected in series; the sub-cell with the greatest radiation degradation degrades the efficiency of the multi-junction solar cell. To improve the radiation resistance of (In)GaAs sub-cells, measures such as reducing the dopant concentration, decreasing the thickness of the base region, etc., can be used [ 66 ].
In the year 1939 Russell Ohl built the first photovoltaic device by using a Si p–n junction diode. The photovoltaic cell material must need to work for a spectral range specifying the solar spectrum. The solar spectrum ranges from the infrared region to the ultraviolet region and it has non-uniform intensity. For maximum exposure to the sunlight the solar cells are wide-area …
A silicon photovoltaic (PV) cell converts the energy of sunlight directly into electricity—a process called the photovoltaic effect—by using a thin layer or wafer of silicon that has been doped to create a PN junction.
