Have you ever wondered how sunlight can travel 93 million miles from the Sun to the Earth, and still have enough oomph in reserve to burn your light bulbs? That, in a nutshell, is the miracle of solar energy. As for how solar panels work, that’s a little harder to fit in a nutshell but […]
As discussed previously, a pn junction diode and a light-generated current are required to model a solar cell. Hence, the simplest solar cell consists of a pn junction diode connected in parallel with the currrent source — shown below in Figure 1. Meanwhile, when there is no light present to generate any current, the PV cell behaves […]
Since a solar cell is the only generator in a solar PV system, it is one of the most important parts in a solar PV system. In the following paragraphs, a simple introduction of a solar cell and how it operates is discussed, with reference links for better understanding. A solar cell: A solar cell is a […]
