Photovoltaic solar radiation conversion is the process of converting solar radiation energy into the electrical energy . The photovoltaic conversion of solar radiation takes place in solar cells made of semiconductor materials, which are of simple construction, have no mobile parts, are environmentally friendly, and have a long-life shelf.
Photovoltaic cells (made of semiconductor material) absorb photons, elementary particles present in sunlight. The absorbed photons excite the electrons present in the photovoltaic cell and the movement of these electrons generates an electric current. In solar thermal conversion, solar energy is stored in the form of thermal energy.
Sunlight can be directly converted into electricity in solar cells via the photovoltaic (PV) effect. This chapter examines the fundamental mechanisms behind this energy conversion process. PV conversion will only occur in a device exhibiting two necessary behaviors.
The use of photovoltaic (PV) solar cells on the ground actually started in the United States around 1978.
On this principle, a combined solar cell of the Si cells (1.1 eV) and AlGaAs/GaAs cells (1.65 eV) was produced, which in the concentrator photovoltaic system has an efficiency of 27%.
In solar thermal conversion, solar energy is stored in the form of thermal energy. The solar thermal energy system uses solar thermal collector panels to capture the sun׳s heat and transfer it to a fluid (usually water). The liquid is heated to a certain temperature.
