photo voltaic cell

Photo Voltaic Cell..

Photo voltaic cell converts light energy into electrical energy. It acts as a cell. It consists of a metal layer of copper over which a semiconductor layer of cuprous oxide coated with a thing film of silver or gol..

The mass of substance deposited is directly proportional to the quantity of current passe..

In order to study the working of an electrolytic cell and the phenomena of electrolysis it is important to know the working of a galvanic or a voltaic cell that generates electrical energy from its chemical reaction. In a simple voltaic cell a zinc ..

Electrochemical Cells - The fact that chemical reactions produce electrical effects was discovered accidentally in 1791 by Luigi Galwani, professor of anatomy at the University of Bologna, Italy. He found that an electric current flowed across two dissimilar metals between which was a moi..

Spontaneous redox reactions are the metal displacement reactions. Therefore such reactions have been used for producing electricity. This is done by carrying out these reactions in specially designed units called electrochemical cells. An electrochemical cell is a device used t..

The heat and light energy emitted by the sun's radiation is called solar energy. Earth receives about 640 J of energy per second per square metre from the sun. The Sun's energy has two aspects. The 'heating effect' of sunlight, which is due to the infrared radiation present in the sun rays and the..

Mechanism of Electrolysis - The process of electrolysis is exactly opposite to one that takes place in a voltaic cell. A voltaic cell or a battery uses its chemical energy to produce electrical energy. While in electrolysis, electrical energy is used to bring..
