Customer ServiceAnd all this is possible thanks to an essential component: the photovoltaic cell. A photovoltaic cell is an electronic device that converts the energy in the solar radiation that reaches the earth in the form of light (photons) into electrical energy (electrons) thanks to the photoelectric effect.
A photocell is a resistor that changes resistance depending on the amount of light incident on it. A photocell operates on semiconductor photoconductivity: the energy of photons hitting the semiconductor frees electrons to flow, decreasing the resistance. An example photocell is the Advanced Photonix PDV-P5002, shown in Figure 21.2.
All these things are examples of photoelectric cells (sometimes called photocells)—electronic devices that generate electricity when light falls on them. What are they and how do they work? Let's take a closer look! Photo: The photovoltaics in these solar panels are just one of the three common types of photoelectric cells.
A photovoltaic cell is an electronic device that converts the energy in the solar radiation that reaches the earth in the form of light (photons) into electrical energy (electrons) thanks to the photoelectric effect. Major milestones in the history of the development of these cells, include:
An array of solar cells converts solar energy into a usable amount of direct current (DC) electricity. An inverter can convert the power to alternating current (AC). The most commonly known solar cell is configured as a large-area p–n junction made from silicon.
A "photoelectrolytic cell" (photoelectrochemical cell), on the other hand, refers either to a type of photovoltaic cell (like that developed by Edmond Becquerel and modern dye-sensitized solar cells), or to a device that splits water directly into hydrogen and oxygen using only solar illumination.
