What is Photovoltaic Effect?


Photovoltaic Effect Definition


The photovoltaic effect is the direct conversion of light energy to electrical energy using semiconductor materials.


 

Semiconductor Role


Semiconductors like silicon are crucial as they facilitate the movement and interaction of electron-hole pairs necessary for electricity generation.

Charge Carrier Dynamics


The movement of electrons and holes across the semiconductor junction is essential for establishing an electric field that aids in electricity generation.


 

Impact of Sunlight


Exposure to sunlight energizes electrons in silicon, leading to the creation of electron-hole pairs and subsequent electrical current.


 

Efficiency Factors


Solar cell design aims to maximize the separation of electron-hole pairs to increase the efficiency of electricity generation.

What is Automatic Voltage Regulator?
What is Automatic Voltage Regulator?
An automatic voltage regulator is employed to regulate voltage, converting fluctuating voltages into a constant one. Voltage fluctuations mainly stem from variations in the load on the supply system. Such voltage variations can damage the equipment within the power system. These fluctuations can be mitigated by installing voltage - control equipment at various locations, such as near transformers, generators, and feeders. Multiple voltage regulators are often placed throughout the power system t

What is Arc Extinction Circuit Breaker?
What is Arc Extinction Circuit Breaker?
When the current-carrying contacts of a circuit breaker separate, an arc forms and persists briefly after contact separation. This arc is hazardous due to the heat energy it generates, which can produce explosive forces.A circuit breaker must extinguish the arc without damaging equipment or endangering personnel. The arc significantly influences the breaker’s performance. Interrupting aDC arcis inherently more challenging than anAC arc. In an AC arc, the current naturally reaches zero duri

Air Break Circuit Breaker
Air Break Circuit Breaker
In an air break circuit breaker, the arc is initiated and extinguished in substantially static air as the arc moves. These breakers are used for low voltages, generally up to 15 kV, with rupturing capacities of 500 MVA. As an arc-quenching medium, air circuit breakers offer several advantages over oil, including:Elimination of risks and maintenance associated with oil use.Absence of mechanical stress caused by gas pressure and oil movement.Elimination of costs from regular oil replacement due to
