The photovoltaic effect is a complicated process, but these three steps are the basic way that energy from the sun is converted into usable electricity by solar cells in solar panels. A PV cell is made of materials that can absorb photons from the sun and create an electron flow. When electrons are excited by photons, they produce a flow of electricity known …
A single solar cell cannot produce enough power to fulfill such a load demand, it can hardly produce power in a range from 0.1 to 3 watts depending on the cell area. In the case of grid-connected and industrial power plants, we require power in the range of Mega-watts or even Giga-watts. Thus, a single PV cell is not capable of such high demand. So, to meet these high …
How a Solar Cell Works. Solar cells contain a material that conducts electricity only when energy is provided—by sunlight, in this case.
