Solar energy converted into electrical energy pdf.

Solar energy with a focus on photovoltaics which is the technology that allows to convert energy transported in light directly into electrical energy. Now that we know that solar energy is a good source of power let s consider how does it work more precisely that it can be converted into electricity using direct or indirect methods. Fortunately you don t have to be a rocket scientist to understand the process of converting solar energy into electricity. In such cells a small electric voltage is generated when light strikes the junction between a metal and a semiconductor such as silicon or the junction between two different semiconductors.

This nuclear energy flux is rapidly converted into thermal energy and transported toward the surface of the star where it is released in the form of electromagnetic radiation. Despite the enormous energy flux supplied by the sun the three conversion routes supply only a tiny fraction of our current and future energy needs. Conversion of solar energy into electrical energy storage. Firstly let s consider the direct usage which by the way is the most common way of receiving electricity from the sun and lies in the usage of solar.

The second one is through photo voltaic where solar energy is converted directly into electricity that could be used for a variety of applications like lighting moving or pumping the third method involves use of thermocouples. Ezcol 2third end solar photo voltaic. Even though communities are flocking toward solar energy and more people than ever are installing solar panels on their homes many are in the dark about the technology that makes it possible. Solar energy solar energy electricity generation.

Solar electric solar fuel solar thermal figure 1. The potential for solar energy is enormous since about 200 000 times the world s total daily electric generating capacity is received by earth every day in the form of solar energy. Solar photons convert naturally into three forms of energy electricity chemical fuel and heat that link seamlessly with existing energy chains. The power density emitted by the sun is of the order of 64mw m2 of which 1370w m2 reach the top of the earth s atmosphere with no significant absorption in the space.

Solar photo voltaic cells work by converting sunlight into electric current. The organisation of this book is roughly linked to the three lectures on photovoltaics pv that are given at the faculty for electrical engineering mathematics and com. Solar radiation may be converted directly into electricity by solar cells photovoltaic cells.
