Phosphorus has five electrons in its outer energy level, not four. It bonds with its silicon neighbor atoms, but one electron is not involved in bonding. Instead, it is free to move inside the silicon structure. A solar cell consists of a layer of p-type silicon placed next to a layer of n-type silicon (Fig. 1). In the n-type layer, there is an

Learn MoreWhen connected either in parallel or in series, these individual solar photovoltaic cells form a solar panel, serving as the fundamental building block of the entire system. The solar cell function is to convert solar energy into electrical current for various purposes. The most common ones include: Energy production for domestic or industrial use.
Solar PV cells consist of two types of semiconductor solar elements – p-type and n-type silicon. The difference lies in the type of charge carriers. An electric field forms between the two semiconductor layers. When a photon of sunlight knocks a free electron loose, the electric field pushes it out of the silicon junction.
Photons striking the silicon semiconductor release electrons from the n-layer, captured by the p-layer, and as electrons move in a circular path, they lose energy, charging the battery. Solar photovoltaic cells are truly wonders of energy with enormous potential to provide a clean and accessible energy source.
