Solar panels consist of a layer of silicon cells, a metal frame, a glass casing unit, and wiring to transfer electric current from the silicon. Here''s how a solar panel system works:
A conventional crystalline silicon solar cell (as of 2005). Electrical contacts made from busbars (the larger silver-colored strips) and fingers (the smaller ones) are printed on the silicon wafer. Symbol of a Photovoltaic cell. 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. [1]
Without getting too technical, photovoltaic cells can be made from either monocrystalline or polycrystalline material, and consist of several layers, the most important of which are the two semiconductors in the centre. The top semiconductor is a negative layer, as the material''s atoms contain extra electrons, which carry a negative charge. ...
When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the "semi" means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal.
