gradual heating and cooling. Solar cells are based on semiconductor physics -- they are essentially just a P-N junction photo-diodes with a very large light-sensitive area. Another common material for thin- film cells include Gallium Aarsenide (GaAs)‚ Copper Indium Gallium Selenide‚ and gallium Phosphide. The most common types of photovoltaic cells are single-junction‚ multi-junction‚ and thin-film. A thin film panel is flexible and can tolerate a bullet hole without failing and can greatly increase

form of waves. The spectrum is made up of different colors that make up the visible light. In lighting‚ LEDs (Light Emitting Diodes) are becoming popular due to their ability to easily produce different types of colors which enhances their aesthetic value. LEDs are made up of a p-n junction diode (semiconductor) which emits light when activated. The color emitted by the diode is determined by the energy band gap of the

FIBER-OPTIC COMMUNICATION Introduction Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic waves that is modulated to carry information. First developed in the 1970s‚ fiber-optic communication system have revolutionized the telecommunication industry and have played a major role in the advent of the information over age. Because of its advantages over electrical

What is Telecommunication? Many people call telecommunication the world’s most lucrative industry. If we add cellular and PCS users‚ there are about 1800 million subscribers to telecommunication services world wide (1999). Annual expenditures on telecommunications may reach 900‚000 dollars in the year 2000. In industrialized nations‚ the telephone is accepted as a way of life. The telephone is connected to the public switched telecommunications network (PSTN) for local‚ national
