Working Principle of Solar Cell or Photovoltaic Cell

Conversion of light energy in electrical energy is based on a phenomenon called photovoltaic effect. When semiconductor materials are exposed to light, the some of the photons of light ray are absorbed by the semiconductor crystal which causes a significant number of free electrons in the crystal.

What is Photovoltaic Effect?

The effect due to which light energy is converted to electric energy in certain semiconductor materials is known as photovoltaic effect . This directly converts light energy to electricity without any intermediate process. For demonstrating the photovoltaic effect let us assume a block of silicon cr

Unit of Electrical Energy

The unit of electric power is watt, and hence unit of electrical energy is watt – second since energy is the product of power and time. The watt – seconds is referred as joules. One joule means the work required to be done for transferring one-ampere current in one second from one point to another p

Economic Dispatch Problem: What is it? (Security & MOE)

What is Economic Dispatch? Economic dispatch (also known as economic load dispatch or merit order) is defined as an online process that allocates the generation among the available generators to fulfill the load demand that helps to minimize the total generation cost. The economic dispatch outlines
