What Is A Solar Cell: How does Solar Cell Work?

In this article you will find answers to the following questions: 1) What Is A Solar Cell, and 2) How Does Solar Cell Work?

In a solar module solar cells are must be protected against environmental influences, as they are very fragile. Today solar cells are used even for small applications such as charging batteries in watches, calculators, and toys. They are applied for traffic signals and lighting as well.

What Is A Solar Cell?

The solar power cells are the common term used for the current devices that convert sun power into free electricity.

 

The solar panels are made from materials like silicon semiconductors which have interesting electrical properties that are useful for electronic devices like microprocessors used in computers.

 

Solar cells are packaged into solar power panels that can be installed on large fields or roofs. Solar cells are usually one of the most expensive parts of a solar energy system.

 

How Does Solar Cell Work?

You have already got an answer to the question: “What Is A Solar Cell?”. Now let’s find out how it works.

Solar panels are devices that convert sunlight into electrical energy. To work properly, cells must be covered with a semiconductor material that is able to absorb light.

 

Solar panels are mostly silicon, the main component of sand. There are no toxic materials to get out of the system. 

 

 Solar energy cells are essentially semiconductor junctions lighting conditions. Light generates electron-hole pairs on both sides of the junction, the N-type emitter and the p-type base.  

 

Conclusion:  

Now you know what solar cells are and how solar pales work. In one word, they are a clean and reliable method of generating electricity which is widely applied mainly to remote applications like telecommunications and marine navigation systems, which requires low maintenance and high reliability.

Solio Classic-i Hybrid Solar Charger


Product Description

With solar panels that are 20% more efficient, the new Solio Classic-i Hybrid Solar Charger (updated 2010) provides more power to more devices more quickly than ever. To promote maximum flexibility in an economically- and environmentally-friendly package, this model does not come with a pre-selected variety of adapter tips (that you may or may not use), but is instead compatible with all i-Go power tips (sold separately). The Solio Classic-i Hybrid Solar Charger is the perfect lightweight travel charger, a primary power source when in remote locations, or an emergency back-up power supply. The Classic-i features a folding three-panel design, three photovoltaic cells plus a full-size charging battery enabling quick re-charging of your portable electronic devices. The Solio Classic-i Hybrid Solar Charger is simple to use. Charge the Classic’s battery one of three ways: directly from the sun using the integrated solar cell, or from your computer using the included USB charge-in cable, or from the included rapid wall charger. The 1,650 mAh internal Lithium-Ion rechargeable battery stores power until you need it – for up to one year. Using the appropriate i-Go power tip, connect it to your electronic device, press the start button and you’re charging on-the-go. Just 1 hour of sunshine = 20+ minutes talk time or 50+ minutes MP3 music (depending on device).

Amazon.com Product Description

With more than one million units sold to date, the Solio Classic is the most popular solar charger on the market. Well now the Classic just got better with this release of the Classic-i hybrid charger, which is more powerful and looks better than ever. With solar panels that are 20 percent more efficient than in earlier models, the Classic-i easily charges all of your handheld electronic products whether you’re at home or on the go. The Classic-i works by absorbing power from the wall socket, a computer, or direct sunlight, and then storing the energy within its internal battery. Once the charger’s battery is full, you can use it to power your cell phone, smart phone, iPod, MP3 player, PDA, Bluetooth headset, game player, GPS, fish finder, or digital camera–more than 3,200-plus devices in all. This versatility helps the Classic-i excel as a travel companion, a primary power source for remote locations, or an emergency backup power supply.

The universal charger is environmentally friendly and cost-effective, as sun-based energy is completely free and creates no harmful impacts. And the solar design couldn’t be simpler, with a fan-blade outlay that achieves maximum solar area when in use. Just spread out the blades, expose them to direct sunlight either outdoors or affixed to a window, and get ready to take your power on the road. You can use the sun to fully charge the Classic-i’s battery for later use, or you can charge your device directly through the Classic-i. One hour of sunshine provides roughly 20-plus minutes of talk time or 50-plus minutes of MP3 music (depending on the device).

To charge the Classic-i’s battery without using the sun, simply connect the charger to your computer using the included USB charge-in cable, or plug the included wall charger into the wall. Plus, the energy in the charger’s 1,650 mAh lithium-ion battery doesn’t need to be redeemed immediately, as it stores the juice for more than a year. The Classic-i does not come with a preselected variety of adapter tips, but is instead compatible with all i-Go power tips (sold separately), including i-Go mini USB, i-Go micro USB, i-Go iPhone/iPod, i-Go Samsung, and i-Go Blackberry versions. The Classic-i hybrid charger measures 2.5 by 1.3 by 4.7 inches (W x H x D), weighs 2.75 ounces, and carries a one-year warranty.

About Solio
The sun’s energy has always been recognized as powerful. How powerful? The amount of energy that falls on the Earth in one hour is the same amount used by the world’s population in one year. With these details in mind, Better Energy Systems created the Solio–a hybrid solar charger for small, portable, electronic gadgets. It was introduced at San Francisco’s MacWorld in 2005, where it won Best of Show. The Solio quickly caught the consumer’s imagination and interest, because it combined convenient, easy-to-use renewable energy with cutting-edge, award-winning design and engineering. With this combined value and appeal, the company continues to receive prestigious awards and acknowledgements for its family of Solio models, and has now sold more solar systems than any other company in the world.
