PV conversion will only occur in a device exhibiting two necessary behaviors. First, a solar cell must absorb solar radiation, converting the Sun’s heat energy into chemical energy in the device. When light is absorbed, electrons are excited into higher energy levels, temporarily storing chemical energy.
When we install solar panels, we are harnessing light energy from the sun. When the light strikes the surface of the semiconductor material, a reaction takes place, which converts the light energy into electrical energy. But since solar panels aren’t 100% efficient, some of this light energy becomes heat.
Solar energy conversion describes technologies devoted to the transformation of solar energy to other (useful) forms of energy, including electricity, fuel, and heat.
Solar cells exploit the optoelectronic properties of semiconductors to produce the photovoltaic (PV) effect: the transformation of solar radiation energy (photons) into electrical energy. Note that the photovoltaic and photoelectric effects are related, but they are not the same.
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.
The conversion rate of solar radiation into electricity by PVs depends on cell type and is between 5% and 20%. Thus, the greater part of the absorbed solar radiation by PVs is converted into heat (at about 60–70%), increasing the temperature of cells.
