The thin film solar panels are one of the newest breakthroughs in the booming solar industry. Compared to their predecessor, they are much thinner and affordable and may well lead to a much wider use of solar energy in near future.
The working mechanism behind the thin film solar panels is the same as their "thick" counterparts. Both use photovoltaic cells to collect sunlight and convert it into electric current through the interaction between the sunlight and the semiconductor material contained in the PV cells. The electricity thus generated can be put into use right away at your home or office. You can also store it with batteries to back up the power at nights or on cloudy days.
What exactly has enabled the thin film PV cells to work with the same efficiency but at a much reduced cost? The answer is in the semiconductor material. The first generation of solar panels, which are the thick ones that we are all used to seeing, use crystalline silicon as the semiconductor material. Each solar cell is produced on a different silicon wafer, one by one. This is an extremely labor-intensive process, which makes the solar panels unaffordable by mass people.
The semiconductor material used in thin film PV cells, as a contrast, is much thinner and cheaper. What's better, it can be mass produced with an automated system and thereby cuts down the labor work by 3 times. You can imagine that, with this reduced cost, more and more businesses will be encouraged to enter the manufacturing of solar panels. If this happens, the prices of solar panels will become even more affordable.
And, there are more exciting applications. With the solar cells being smaller, they are also more light-weighted and can be flexibly placed onto various smaller and light-weighted objects. For instance, the solar roof shingles are produced by covering the traditional asphalt roof with a layer of thin file solar cells. Now, instead of holding your solar panel with the large and heavy steel arrays, your solar roof can look almost the same as that of your neighbors.
Portable solar panels are another product of the thin film technology. They are being manufactured to power up just any type of electric appliances, from cell phones, GPS devices, MP3 players, to televisions and laptops. How handy it will be if you can install a solar panel on your backpack or in your purse? You can carry it wherever you go and charge your portable electric devices whenever needed.
If the thin film solar panels still sound to you like a complex technical innovation rather than an easily accessible daily product, don't worry. Think about the digital watches. They cost dearly a few decades ago, but can be purchased today at a very friendly price. This will be the future of our solar panels!

Protection with Security Laminates and Safety Films
ID Card Security Laminates
Adding lamination to the application will increase the card's life, secure the data on the cards, and increase the security of your offices. There are several types of generic security hologram material and clear (no hologram) laminates. Many business opt for the convenience of a generic material, whereas others prefer the enhanced security of a custom laminate.
Two diffrent typs of laminate materials categories, Hard coat (patch style) and Thin film (or Soft Coat). Hard coat lamination assures superior protection against color fading and scratching. 1mil Hard coat material stands up to the rigorous durability testing regularly performed by driving license authorities globally. Hard coat material is available in a standard 1mil (.001 inch) or custom .5 mil (.0005 inch) thickness.
Thin film laminate is unique, because it is the only material on the market that is designed to adhere to the ribbon's overlay panel applied by the print head. Therefore, it provides enhanced dye migration and fading protection.The Soft coat material can be applied edge-to-edge and offers up to 500 images per roll versus the Hard coat's 255 images per roll.
Custom security features can be designed into both Hard coat and Soft coat material and are common for clients interested in using their cards as visual security passes - sometime called "flash passes".
Safety Films
Burglars hate being caught.Delay entry, and even a professional burglar will flee and look for an easier target.
When you install Safety Films security laminate glass coatings, you take away a thief's easiest points of entry. When laminate-treated glass is broken, the sheet of security laminate and the anchoring system hold the glass fragments in place, creating an impenetrable barrier. This smashed-glass barrier dissipates the force of any further blows, denying the burglar entry.
Used in conjunction with alarm systems and good locks, window security laminates provide effective protection for your home, business, or industrial facility. While nothing can guarantee to keep criminals out of your home or business, eliminating the speed and ease of entry that they rely on is usually enough to keep you from becoming their next victim.
Safety Films security laminates turn vulnerable glass into "invisible walls". Security laminates will help you to protect:
- existing and new glass
- doors, basement windows, garage windows-everywhere that glass is a possible point of entry
- homes, offices, retail stores, commercial & industrial properties, churches, hotels, etc.
- police cars, executive vehicles, private automobiles, and buses
- government buildings
Safety Films security laminates are manufactured from 2,3, or 4 layers of flexible polyester film, bonded together to form virtually invisible scratch-resistant coatings. The laminated glass can be safely cleaned with any non-abrasive glass cleaner. Unlike burglar bars, Safety Films security laminates are virtually invisible. Best of all, your sliding and catch-style windows will still open normally after the security laminate is applied, so you're not trapped inside your building the way you would be with ugly burglar bars.
- A single break-in can equal:
- damage to carpets & furniture from broken glass
- possible weather damage
- expensive & unsightly boarding up
- losses not covered by insurance (e.g. heirlooms and sentimental possessions)
- downtime
- lost data
- lost peace of mind through stress and feelings of violation & vulnerability
- increased insurance premiums
Safety Films security laminates can help eliminate all of the above. Since the film usually survives the attack intact, you won't have to arrange temporary boarding-up to protect the building's contents until the glass can be replaced.
To help protect carpets and other valuables from fading or solar damage, all our security laminate products provide 98-99% UV reduction. It also create a 1R insulation effect that helps reduce your heating bills.
Safety Films security laminates are cost-effective glass protection. Many home and business installations have cost less than the deductible on our customer's insurance!
Safety Films: Protect Yourself From Glass Breakage
Whether it's caused by a stray tree branch or a vandal, broken glass is dangerous. Broken window and door glass can result in:
- injury to people
- glass damage to drapes and carpets
- weather damage (what if it's raining when the window breaks?)
- opportunistic access for vandals and thieves

Is Steve Irwin a suitable figure to view as an Australian hero?
Steve Irwin died on September 4 2006 when he was fatally pierced in the chest by a stingray barb off the Great Barrier Reef whilst filming for his daughter Bindi Sue's show Oceans Deadliest. Do you think Steve Irwin is a suitable figure to be viewed as an Austalian hero?
I can't think of a better one He was a real man in every sense of the word and a great Australian
CIMM Fest: Burning
This is part of Chicagoist's coverage of the Chicago International Movies and Music Festival , which runs March 4-7. We find that live performance recordings tend to be hit or miss. Half a concert's mojo is based on the fact that you are there, in the flesh, able to absorb all the intricacies that make up the show. This ends up being the downfall of most recordings -- the detachment diminishes ...
Thanks for visiting!
