38 % Increase in Solar Panel Efficiency By Injecting Fluorescent Dye

polymer-dyeImagine increasing solar panel efficiency a dramatic 38 %? They have just done this by injecting fluorescent dye into solar panels.

So what’s the catch? I was looking for the catch because that is a darn right big number and definitely helps in slashing the cost per square foot of solar panels.

Scientists at Yale actually coated the panels with fluorescent dye but I said injecting because it sounds a bit more like mad science.

Polymer solar cells are great because they are flexible, cheap, and thin but they only convert about 50 % of solar heat into electricity.

This has all changed because when coating the cells with dye they all the sudden compete with the more expensive panels but their benefits remain the same.

Scientifically what is happening when the dye is applied is that  the organic squaraine dye increases light absorption and recycles electrons, which speeds up the light to energy conversion process.

This new technology will be used in the production of future solar cells and if your interested in learning more about it you can find the entire research article in the Nature Photonics journal.

Solar Panel Home Windows, Transparent and Affordable

There has been a recent development and practical application of a transparent solar panel created by UCLA with a substance I can only describe as “glass like plastic”

Imagine having solar panels with the practical ability to act as windows so you can see outside and yet they are creating energy at the same time?

The greatest part of this new invention is that they can be made very afford-ably and solve the problem of how to make windows into solar panels.

I am sure many others have thought, “If we could just make solar panels transparent we could power skyscrapers”

As you can probably tell there will be numerous practical applications for solar panels that double as windows and skyscrapers is just the tip of the iceberg here.

The University of California, Los Angeles says these polymer solar cells produce energy by taking in almost all infrared light, allowing the window solar panels to be about 68 per cent transparent to us humans.

The windows were made from photo-active plastic which provides a way to turn infrared light into electricity.

The ability to produce these new solar cells at a high volume and low cost has got me super interested in these things.

I imagine cell phones and a majority of other electronics will one day incorporate these things into their functionality.

These solar cells were invented in the California NanoSystems Institute which is no surprise to me as nano technology continues to make strides in many new breakthrough inventions that are created.

The nano part of this technology is the small silver nanowire composite film that is put as the top transparent electrode. These panels are able to absorb a lot of near infrared light but not as much visible sunlight which is the trade off that allows for them to remain transparent.

The nano-mixture is silver nanowire and titanium dioxide nano-particles which allows for transparency and not just opaqueness as has been all that could be achieved in the past.


Solar power for Electric Tools and laptops

Sunshine Solar Briefcase Charger Amorphous 13 Watt

This solar panel is very affordable and the perfect first time solar project starter. You can use this when you go out to remote areas to build and work on a cabin in the woods and other places not accessible to electric pole and wires. If you have a drill or saw that needs power you can charge it up on the solar panel and keep working without having to go back to the house and get the battery recharged.

Need more power?

The 30 Watt 12 Volt solar panel charger will handle the larger laptops and power tools. Have your batteries charging while working in remote locations. Trade batteries and keep going. No need to stop working even when far out in remote locations. This will keep you going no matter where you are.

Product Description

This 30 Watt Mono-crystalline Portable Briefcase Solar Panel 12V Charger is just the thing for your power tools and laptop computers.

30 Watt Mono-crystalline Portable Briefcase Solar Panel 12V Charger. If you need to use it to charge a car battery, you may need a charge controller to prevent the battery from overcharging. Detachable connections included: alligator battery clamps, male cigarette lighter plug, and female cigarette lighter plug. There are three types of Solar Cells on the market. All our Solar chargers are using the best – Mono-Crystalline Solar Cells. Amorphous or Dual Junction Solar Glass are the cheapest but are only 7% energy efficient and have 5 years of service life. They are big and heavy. Poly-Crystalline have 25 plus years of service life under direct sunlight and are 13% efficient. Mono-Crystalline have 25 plus years of service life and are up to 20% efficient. This is the same type used in solar car racing. This type of solar cells is now in a worldwide shortage because only a few companies can manufacture these solar cells.
