Is made of conventional silicon solar cell thickness of 1%
As early as 10 years ago, scientists invented a hair, even smaller than the solar cells, because they use the semiconductor material is less than ordinary solar cells, so the high price of solar cells to resolve the issue. Later, the researchers used known as the CIS compound semiconductor technology, will be 2 to 3 microns thick on the glass material on the CIS, made of thin-film solar cells. Than conventional silicon solar cells made from thin 100 times thinner than a human hair in fact, it is also lighter and use less semiconductor materials, prices are cheaper and can therefore mass production.
Traditional silicon cells need a large number of semiconductor materials, is expensive and therefore can not be universal, and because of the more cumbersome, and their use is restricted. Thin-film battery only needs to be placed on low-cost materials such as plastics and flexible surfaces can be inexpensive and lightweight.

Button Battery – IBM Battery
Alone inside a button to replace watch battery, even earning an average of 1,500 yuan per month, which may cause not very confident, but it is indeed a true story.
5 years ago, from Chaohu, Anhui Province, a 20-year-old girl, in my district where placed in front of a button to replace watch batteries stalls next to also shore up a billboard that reads, “Please be assured of : The cabinet sold by certain licensing button batteries, purchased from approved sources to authentic, and each pill is approved purchase cost 5 yuan, plus a variety of fees to be paid, so the sale price set at 10 yuan. Welcome to presence of the cabinet to replace the battery, from the date of replacement, if the battery less than two years, I unconditionally to 10 times the original price to be compensation. “inducing effect of such advertising, this rapidly booming business pitch up dell xps m1710 battery , dell xps m1730 battery. At the same time, everyone’s commitment to this girl is also very appreciated.
Well, this girl is how to fulfill its authoritative, it? Recently, I witnessed the unusual move of her: She watches every customer to replace a button battery, it will pocket out of a China brand pencil case back to the inner walls of the table to sign the name of his own mini – When will the day as well as a few minutes, and then tighten the table cover, calibration time Didao customer hands, and smiled and said: “You watch where have my mark, under normal circumstances, this grain button battery, if less than 2 year, please come to me, I will compensate your loss, believe me. “When the customer took delivery to 10 dollars later, she re-invoicing.
“Proof of the pudding, something a long time see the people.” Sure enough, when the customers come back the next time when the replacement button batteries, unscrew a case back look at the dates, are more than two years, and some have even gone almost 3 years.
By contrast, some booths and even some stores to customers the same button to replace the battery, even though the price is relatively cheaper, but it can not be “launched” to two years, its authentic or not, find it difficult to distinguish. Eat a cutting wisdom, so more and more customers to vote in order to praise the girl’s attention, have let the girl inside the button to replace watch batteries. As a result, their business several times higher than others naturally. It is learned that since four years ago, this girl more than 10 pieces a day to replace watch battery button to remove a variety of costs, guaranteed profits, 50 yuan is not a problem.
Said is now difficult to do business, put it bluntly, it’s difficult to be in what state of mind and know-how to do that in good faith under the premise of how to use one’s opponent to tap the dell xps m1210 battery , dell xps m1330 battery , dell xps m1530 battery business, the details of the door, this might be the girl given the greatest inspiration.
