Multijunction Solar Cells - Technology Imitates Nature

Remember your basic Biology 101 and photosynthesis?

In case you need a refresher on the topic, photosynthesis is how a plant converts light into energy, which it uses to run its metabolic processes. Multijunction solar represent the mechanical, artificial analogue to this biological process. But before we get into that, let's take a look at your basic solar cell.

 

It's Been Around Longer Than You Think

The idea of generating electricity using sunlight dates back almost to the time people started using electricity. In fact, a photovoltaic effect was first produced around 1840 - not long after Queen

The Nanotechnology Solar Cell Revolution

     There is little debate that we need to wean ourselves off of fossil fuels, but the costs of renewable energy platforms such as solar make it difficult. Nanotechnology definitely offers the answer.
Solar power is considered one of the better renewable energy platforms. Enough sunlight hits our planet each day to meet our world wide energy needs for an entire year. On top of this, solar energy is a free power source, since nobody can corner the market on the sun. Solar power is also good for the environment since it produces none of the emissions that are of such concern today, specifically carbon dioxide greenhouse gases.
If solar is so great, why don't we see more practical applications? The problem lies in the applications. Specifically, we have no way to harness the power. Commercial solar cells are very inefficient. Current models on the market only convert about 8 to 13 percent of the sunlight hitting them. This inefficiency makes the cost of producing energy via solar platforms too costly. So, what can we do?

Solar Gadgets Can Save Lives

Mobile Solar-powered Camel Hospitals

The right solar gadgets can save your life, if you are prepared. There are many tools, medical kits, and other life saving equipment out there, but are you choosing the right ones. A lot people stock up on batteries, which end up in spending a lot on batteries. The main reason that people are stocking up on batteries are for flashlights, lanterns, other portable electronics, well today I will tell you one tool that can and will save your life.
I was skimming though out the internet looking for some emergency supplies and I came across a device called the Hybrid SolarLite. This sounded really cool, and the price looked even better. I did some research and I even called Linda, she is one of the top ladies there. She told me some very important useful information I will share with you.
If you were to buy this solar flashlight it can last a single charge for 3 years. That is really awesome because when I have an area in my home for emergency supplies, I usually like to know that every works. I found out that 8 hours of charge in the sunlight, but hear this in roomlight will last up to 10 hours of continuous light.
One of the things I learned was that if you charged this solar gadget everyday, because you had to use it everyday you would be buying new batteries for free like every 5 hours because the batteries are rechargable. WOW...That is where they sold me. To think that I never have to buy new batteries for my emergency flashlight, and as long as there is sunlight, which just in about every country at least 1 or 2 times a week the sun shows itself. That the solar charger will be recharged for free. This solar gadget realistically pays for itself in about month if you were to compare it to how many times you buy batteries for your flashlight over a course of 6 months. I really like this product and I highly recommend it.
The other feature is that it is waterproof up to 80 feet. I am not a diver or big time swimmer, I figured people would love to know in case they fish at night, or swim, or boat. But do not worry about losing it in the water because it floats. This is a super packed about 5 in one flashlight, which will actually last.
I read somewhere and watched their videos which said it is perfect to put in your glove box or fishing box, boating cargo area. You can place these Solar Gadgets anywhere and use it anywhere!

Solar Spot Lights - Highlight the Best Features of Your Garden

Solar Spot lights are handy fixtures that are used to draw attention of the onlookers on to a specific location. These small and trendy solar spot can be installed in gardens and are also safety options for sprawling spaces.

Conventional spotlights involve cable laying and digging up of the yard, which will destroy the ambience of your garden apart from costing a fortune. Solar lights sans cables can be used to light up water bodies, rock

gardens or an exotic color bed with style. Many homeowners also use solar lights to light up the perimeters of their homes, making it safe and welcoming during night hours. The dark and creepy corners of the yard a narrow doorway also could be ideal places where you can put solar spot to make it bright.

How Solar Electricity Can Save You Money - And Make You Some Too

In rural areas particularly, the cost of drawing from the nearest power grid far exceeds the cost of solar panel power, and the gap is increasing fast. And more and more many households in all sorts of areas - rural, suburban, and urban alike - are turning to home solar panel system as a source of backup power in case of a blackout or other emergency.
The cost of solar panel power per kilowatt hour is admittedly not the absolute cheapest of renewable energies - at around $0.55 per kWh as compared with $0.05 for wind or $0.06 for micro-hydroelectric, for example - but it's still markedly cheaper than paying the power company (especially with rate increases as much as 10% per year), providing of course - and here's the key: that you do it right.
If you're considering installing solar power in your home, then first things first: keep in mind that if you're planning for solar power to provide for all your home's energy needs, the cost of solar panel may take a significant up-front investment.
