CFL
bulb
CFL bulb, A compact fluorescent lamp (CFL), also known as a compact
fluorescent light or energy saving light (or less commonly as a compact
fluorescent tube [CFT]), is a type of fluorescent lamp. Many CFLs are designed
to replace an incandescent lamp and can fit into most existing light fixtures
formerly used for incandescents |

- an example of a natural capacitor clouds and the ground can act in unison to mimic a huge natural capacitor. This tutorial shows how the
collisions of dust with ionizing radiation can cause electrons to be knocked off of particles, creating a charge separation in the clouds, resulting in

Inside PV Systems
What goes on inside a photovoltaic (PV) cell? How can it turn sunlight into
electricity? Find out on this virtual tour of a PV cell. Watch photons, atoms,
and electrons interact to produce an electrical current |
MPPT A maximum power point tracker (or MPPT) is a high efficiency DC to DC
converter that presents an optimal electrical load to a solar panel or array and
produces a voltage suitable for the load |
Photoelectric effect
A freshly polished, negatively charged zinc plate looses its charge if it is
exposed to ultraviolet light. This phenomenon is called the photoelectric effect |

Photoelectric effect
This applet shows you the effect of light on various metals |
Photovoltaic cell animation
The photovoltaic cells rely on a phenomenon
called the photoelectric effect to directly convert sunlight into electricity.
All light carries little bundles of energy called " photons ". When photons
strike certain materials they cause it to emit electrons, Photovoltaic cell

Solar cell operation
solar cells convert light energy into electrical energy either indirectly by first converting it into heat, or through a direct process known as the photovoltaic effect. The most common types of solar cells are based on the
photovoltaic effect, which occurs when light falling on a two-layer semiconductor material produces a potential difference, or voltage, between the
two layers |

Solar cell animation
When energy is received from the sun in the form of photons, some
of the photons are absorbed near the junction, freeing the electrons and
holes in the silicon. The photons of light give enough energy for the electrons
to cross the junction, where they can be picked up on the metal contacts on the
surface of the solar cell and move through an external circuit. After moving
through the external circuit and performing work (such as powering a lamp or
motor) the electrons return to the solar cell |
Solar cells Photodiodes and solar cells work in the reverse sense to LEDs.
If a photon of sufficient energy strikes the valence band in the transition
region ( also known as the diffusion region ) of the diode, an electron can be
promoted to the conduction band by the photoelectric effect leaving a hole in
the valence band. The internal electric field ensures these separate and are
available to an external circuit |
