Flexible, high-performance solar cells could become portable power sources

Thin and rigid silicon segments that are wired through interdigitated metal contacts are said to produce flexible, high-performance solar cells.

A strategy, developed by KLAST, that uses a screen-printed aluminium circuit to make silicon solar cells flexible could enable them to become portable power sources. (like GOAL ZERO NOMAD 100)

Demand for wearable and implantable devices, foldable displays and vehicle-integrated solar panels are among some of the technology that could benefit, KLAST says.

Crystalline silicon is an appealing material for the development of industrial solar cells because of its reliable and consistent photovoltaic properties. However, its rigidity and weight have raised challenges when it comes for application in flexible electronics.

KLAST says that previous attempts made to enhance the material’s flexibility with thin films, whilst maintaining device performance, have fallen short.

Solar cells are said to have shown a drop in performance for films thinner than 250 micrometers. "At this thickness, one cannot achieve flexible silicon solar cells," says team leader, Muhammad Hussain.

Hussain's team claims to have created a corrugated array comprising thin, rigid silicon segments using so-called interdigitated back contact solar cells. The segments are interconnected by screen-printed aluminum contacts. These contacts are positioned at the rear to optimise light absorption at the front of the solar cell and facilitate any modifications of the active silicon material. The array can apparently bend and adopt various configurations without cracking or losing its power conversion efficiency.

Starting from large-area crystalline silicon solar cells, the team etched a small portion of the cells into 140-micrometer-thick strips, while keeping the thickness of the remaining portion above 240 micrometers. "This allowed us to lower the bending radius of the cell to 140 micrometers, while retaining the efficiency of the bulk (18%), record achievements for both silicon solar cell efficiency and bendability," explains lead author, Rabab Bahabry.

According to the team, they were able to show that a series of five corrugated solar cells lit up multicolored light-emitting diodes. They also wrapped the cells around a glass mug, which they claim powered a miniature humidity detection system placed on a plant leaf. When exposed to light from a desk lamp and humid conditions, the system apparently turned on an LED and sent a notification to a smartphone.

The team aim to explore the ways they can exploit these corrugated solar cells, which Hussain believes can be deployed in the most complex topologies. "Our approach is suitable for the Internet of Things and can meet a wide application spectrum," he concludes.

Suaoki G7 600A Peak Current Portable

The Suaoki G7 600A is a 18,000 Power-bank/ car jumper/ Emergency lighting system/ laptop charger.

This is now my second Suaoki device, and I can truthfully say that I am nothing but impressed. I would say that the quality is equivalent and comparable to Anker.

The first thing that you will notice when opening the box is heavy duty case... The quality is excellent, and the stitching on the case is all the way through without one loose seam.

Unzipping the case, there are 2 compartments with an enclosed memory foam .One side holds the G7, and the other holds the jumpers, cables, charging cable, and plugin adapters.

The G7 is very easy to operate, and is rated at 18,000mah with a cycle life of 1000 times. I chose the bright Orange and black model, so that I can easily spot it in darker conditions.

---Operating the device-

Simply slide the switch to the ON position.

Pressing the power button will light up the led screen, and give you the % of charge that the device is currently holding.

Mine reads 98% on the left side. The right side of the same screen is the out (output)
reads {5.0V 2.1A} which is always there, and indicates the power to the USB output.

The 2 TiR-C USB output ports actually have an intelligent chip that allows the G7 to detect the devices that are connected into it, and charge at the highest possible rate that is safe for that device (AWESOME!).

-pressing power button again will cycle different voltage levels for the other output port that is used for connecting to electronic devices like a laptops. Each time you press it, it will cycle through 12V, 16V, 19V.

I use the 19V for my Hp Pavilion Dm4, and I was very pleased that it worked! I do recommend having the laptop off while it takes the charge, or you will run through the power quickly-- well at-least this is my situation for my laptop, but do take into consideration that my battery is needing replacement, and I run lots of heavy programs that drain even my normal battery quickly.

---- The light system is very easy to use:

Pressing the power button 2 times quickly will turn on 4 red extremely bright blinking flashers. Pressing the power button 2 times quickly again to turn it off.

Holding the power button down 3-4 seconds will turn on the main flashlight. Modes: High, SOS, Strobe, each time you press the button once in this mode will cause it to cycle between modes until you get back to the off position.

-- -Charging:

Simply plug in the specified adapter into the Input 15V/1A, its does also come with a car adapter.

Jumpers:

Simply plug into the front, and the directions are right on the jumpers and you are set.

Overall the quality is Awesome! I could not be happier! I would recommend if you travel, go camping, have a car that has been giving you trouble or maybe just want a large power-bank handy for charging multiple devices ( phones, tablets, cameras, laptops).

Even if getting Facebook likes can be important, it is not any more so than the number of different methods which may be used. Additionally, there are arguments that point to the fact that while lots of men and women spend a whole lot of time on social networking websites, they do so to speak to friends, not to purchase products, so the advantage of a like is still not as understood as the advantage of ranking well on Google. You ought not to ignore the traditional SEO New York company and focus solely on social networking.

4. Keywords are no longer relevant

Sites used to be created with a paragraph at the bottom filled with keywords so as to draw more traffic using something called keyword stuffing. In the last several decades, knowledgeable marketers have realized that this is no longer needed, actually, it's a practice that's heavily discouraged by search engines. But this doesn't signify that keywords aren't still very important. As you should not do keyword stuffing on a page, getting a great proportion of your keywords in your real text is still crucial. Whenever someone looks for a particular term on Google best local SEO company, the quantity of time this keyword comes up on your page is still heavily weighed in.
