Solar Cells

Sensors and transducers are devices that are used to detect and measure various physical quantities, such as temperature, pressure, humidity, light, and motion. They are an essential part of many different types of electronic and mechanical systems, as they allow these systems to respond to changes in their environment. Solar cells, also known as photovoltaic cells, are a type of sensor that is used to convert sunlight into electricity. A solar cell consists of a thin layer of semiconductor material, such as silicon, which is sandwiched between two electrodes. When sunlight hits the cell, it creates an electric current, which can be collected by the electrodes and used to power electrical devices. Solar cells are commonly used in solar panels, which are arrays of solar cells that are connected together to produce a larger amount of electricity. Solar cells are also used in a variety of other applications, such as in calculators, watches, and space satellites.
