FAQS about Which side of the solar cell faces the light
What is the P side of a solar cell?
The p-side is relatively thick and is at the back of the solar cell. Both the p-side and the n-side are coated with a conducting material. The n-side is coated with an anti-reflection coating which allows visible light to pass through it. The main function of this coating is to reflect the IR (heat) radiations and protect the solar cell from heat.
How do half-cell solar panels work?
Half-cell (also known as cut-cell) solar panels use traditional-sized solar cells cut in half. This results in a pair of separate cells that are then wired together to form the solar panel, effectively creating two smaller cells out of a single, standard-sized solar cell.
What are bifacial solar cells?
As the name suggests, bifacial solar cells have two “faces”. Like traditional solar cells, bifacial solar cells are typically built with crystalline silicon. Unlike traditional solar cells – which absorb light from the front face alone – bifacial cells are designed to capture sunlight on both sides.
Where are bifacial solar panels located?
Vertical solar panels, east to west orientation, with bifacial modules near Donaueschingen, Germany. A bifacial solar cell (BSC) is any photovoltaic solar cell that can produce electrical energy when illuminated on either of its surfaces, front or rear.
How does a solar cell work?
This coating works as the electrical contact of the solar cell. The contact on the n-side is called the front contact and that at the p-side is called the back contact or the rear contact. The n-side of a solar cell is thin so that the light incident on it reaches the depletion region where the electron-hole pairs are generated.
Do bifacial solar cells produce more electricity?
With a transparent rear side, bifacial solar cells can absorb light from both the front and rear sides. Hence, they can produce more electricity than conventional monofacial solar cells. The first patent of bifacial solar cells was filed by Japanese researcher Hiroshi Mori, in 1966.
