The most commonly known solar cell is configured as a large-area p–n junction made from silicon. As a simplification, one can imagine bringing a layer of n-type silicon into direct contact with a layer of p-type silicon. n-type doping produces mobile electrons (leaving behind positively charged donors) while p-type doping produces mobile holes (and negatively charged acceptors).

However, this is a small effect, and the temperature dependence of the short-circuit current from a silicon solar cell is typically; or 0.06% per °C for silicon. The change of I SC with temperature is more dependent upon the design of the cell than the semiconductor material properties.
Solar array mounted on a rooftop A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
