Turbines convert kinetic energy from fluids into mechanical energy for power generation.
Kinetic energy from moving fluids (water, steam, gas) is transformed into mechanical energy.
In hydro turbines, water flow drives the blades, generating electricity.
Steam turbines convert thermal energy from steam into mechanical energy.
Gas turbines use high-speed gas flow to turn the turbine and produce power.
Photovoltaic cells convert sunlight into electricity using the photovoltaic effect, primarily through semiconductor materials.
Photovoltaic cells are made of semiconductor materials like silicon.
When sunlight hits the cell, photons excite electrons, creating electron-hole pairs.
The electric field in the cell drives the electrons towards the conductive plates, generating direct current (DC).
