What is a diode / LED / solar cell?
This page titled 10.7: Diodes, LEDs and Solar Cells is shared under a CC BY-SA 4.0 license and was authored, remixed, and/or curated by Chemistry 310 (Wikibook) via source content that was edited to the style and standards of the LibreTexts platform. Diodes are semiconductor devices that allow current to flow in only one direction.
Why do solar cells use diodes?
Solar cells generate DC, but at night that flow can reverse as the cells act like loads drawing current. Diodes block this reverse current to ensure the solar cells operate efficiently. Second, diodes are wired into the circuit to force electrons freed by the photovoltaic effect to flow in one direction around the circuit.
What does a diode do?
Diodes are semiconductor devices that allow current to flow in only one direction. Diodes act as rectifiers in electronic circuits, and also as efficient light emitters (in LEDs) and solar cells (in photovoltaics). The basic structure of a diode is a junction between a p-type and an n-type semiconductor, called a p-n junction.
How does a solar cell differ from a junction diode?
A solar cell functions similarly to a junction diode but has a different construction. Instead of a typical p-n junction, a solar cell has a very thin layer of p-type semiconductor grown on a relatively thicker n-type semiconductor. Then, a few finer electrodes are applied on the top of the p-type semiconductor layer.
What is the difference between a solar panel and a photodiode?
Both are photovoltaic semiconductor devices. A solar panel is a biased pn junction diode, whereas a photodiode is an opposite way pn junction diode. Nevertheless, solar cells are built for energy conversion efficiency, whereas photodiodes are designed for light detection. Solar cells and photodiodes are both photovoltaic emiconductor devices.
Which diode is best for solar panels?
Other diodes include Schottky diodes using metal-semiconductor junctions, Zener diodes for regulating voltage and light-emitting diodes (LEDs) that give off light. But for solar panels, the standard semiconductor diode is the workhorse. Solar cells convert sunlight into electrical energy using the photovoltaic effect.
