Staebler Wronski Effect

When light strikes on hydrogenated amorphous silicon it exhibits a metastable change in the photovoltaic properties. When hydrogenated amorphous silicon is exposed prolonged to the light its efficiency to produce electricity decreases that is called Staebler Wronski Effect. This degradation of the electrical output of hydrogenated amorphous silicon is due to prolonged illumination. David L. … Read more

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 crystal. The upper portion of this block is doped with donor … Read more

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. This is the basic reason for producing electricity … Read more

Solar Electricity

The electricity produced by direct hitting of sunlight on photo – voltaic cells, is called solar electricity. Solar Electricity When sunlight strikes on photo-voltaic solar cells, solar electricity is produced. That is why this is also referred to as Photo Voltaic Solar, or PV Solar. Principles of Solar Electricity Generation of electricity by using solar … Read more
