One of the most important parts in PV system architecture is the power converters. The reason is that they play an important role in transforming the different types of electricity, to make the electricity convenient to the end users. Since the solar cell produces a DC type of electricity, there’s room for various types of […]
Since the first solar cell was produced by Bell Labs in the 1950s, solar photovoltaic (PV) technology has been gradually evolving. The work resulted in the development of a compound which is formed of semiconductor elements found in the periodic table and the synthesis of an organic solar cell. Broadly, photovoltaic technologies are now classified as: crystalline silicon solar cells, […]
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 […]
A simple solar photovoltaic (PV) system consists of the following basic components: A solar cell: A solar cell is a solid-state electrical device (p-n junction) that converts the energy of light directly into electricity (DC) using the photovoltaic effect. A solar cell is categorized as a multi-junction cell, single-junction cell, crystalline cell, thin-film technology, or some of type […]
