Solar cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms.
A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode.
Solar cells are used to create electricity from sunlight, specifically photons. They are used in satellites, businesses, to power homes, and even in calculators and toys. Are you a student or a teacher? Learn what a solar cell or photovoltaic cell is and understand how solar cells work.
A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light.
When solar energy hits solar cells, the electrons in the materials are freed and can be induced to travel through an electrical circuit. This direct current (DC) can power electrical devices or be sent to the grid. Solar cells produce DC, which is then converted to alternating current (AC) by using an inverter.
Solar panels are made of multiple solar cells that harness energy from the sun to create electricity. The main part of a PV cell contains numerous semiconductor materials set up in layers to do this. Inside the cell is a p-type layer and an n-type layer. Between the two is what is called the pn-junction.
