A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.
Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.
The operation of a photovoltaic (PV) cell requires 3 basic attributes:

That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy. Lesson by Richard Komp, animation by Globizco.
How to make a solar cell easily (the most simple way still affordable a general family). The technology is there for you.
This "how to make a solar panel" video shows how to connect everything together including all wiring, soldering and cell layout (using tabbed solar cells). Full easy instructions. if you are using "untabbed" solar cells watch my video on "Solar Cell Tabbing". (tabbing is very easy to do). items can be bought as a kit on ebay. for about $48.00 you can get 40 solar cells, tabbing wire, bus wire, flux pen and even blocking diode. i used lead free rosin core solder from harbor freight. cost about $2.50. soldering iron is just a basic 30 watter. the third (and final) video will show how to encase/enclose the panels in either a plywood box or metal framed case.
This introduction to solar cells covers the basics of PN junctions, optical absorption, and IV characteristics. Performance metrics such as efficiency, short-circuit current, fill factor, and open-circuit voltage are discussed. Key technology options and economic considers are briefly introduced. on nanHUB: http://nanohub.org/resources/11875
A laser-based manufacturing process from the Fraunhofer ISE in Freiburg, Germany is revolutionizing the photovoltaics market. For the first time point-contacted solar cells can be manufactured in series. Several million cells with significantly higher efficiency levels are already on the market.

Homeowners with a sun exposed roof can save 20% on Electricity with residential solar panels. Call 855-403-2551 Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells. Electrical connections are made in series to achieve a desired output voltage and/or in parallel to provide a desired current capability. The conducting wires that take the current off the modu...

Timothy Kelly 2014-2015 Seminar Series February 18, 2015 Solar cells based on the perovskite-structured light absorber CH3NH3PbI3 have recently emerged at the forefront of solution-processable photovoltaic devices, with power conversion efficiencies as high as 20.1% having now been certified. In this presentation, I will discuss our research group’s work in the area of perovskite solar cells. Our early work demonstrated that room temperature solution-processing techniques can be used to prepare devices on flexible substrates while retaining excellent power conversion efficiencies. Since then, we have examined issues related to charge carrier diffusion, interfacial contacts, and device flexibility, with our most recent efforts focusing on probing device failure mechanisms using in situ syn...

In the first part I will discuss how in conventional Si heterojunction cells the parasitic absorption in the thin amorphous layers at the front side can be reduced by...
I turned myself unto myself
and asked myself who you are
well, you made me
but what do I love
when I'm with you
I WONDER WHERE YOUR TOUNGE HAS BEEN
BEFORE YOU TASTED MINE
BUT YOU'LL NEVER LET ME KNOW
I'VE BEEN BAD AND I HAVE SINNED
BUT YOU'LL NEVER LET ME GO...
I've done sone grim things
I'vedone really bad things
but I'll never let you know
it's you that I love
in sleep when I'm awake
I won't think as long as you don't
I WONDER WHERE YOUR LIPS HAVE BEEN
BEFORE THEY TASTED MINE
WHERE HAVE YOUR LIPS BEEN TONIGHT?
YOU'VE WRAPPED A RING AROUND MY NECK AND
YOU'LL NEVER LET ME GO
do you think of me- do you think of me?
do you think of me when you are in me?
I just want to know think I ought to know
what you fell
do you turn on me - do you turn on me?
do you turn on me like I turn on you?
don't play tricks on me- don't you lie to me
