In the case of smart phone battery technology could not break through, increased battery capacity, charging people compromise at any time. Of course, people can choose to put the cell phone charging in the Sun, provided that the mobile phone has a built-in solar cells, so even if it is out or securing power, to extend the service time.

Now there are many companies and institutes in the development of this technology. And people think the battery is placed in the back of the fuselage is different, they studied how to implant a PV Panel, or glass. Massachusetts Institute Ubiquitous Energy of a startup is developing a transparent material, which absorbs infrared, ultraviolet, while allowing light to pass through. Researchers at the University of Cambridge in the other development, integration of solar cells and OLED screen, captured through light pixel gap.
PV modules on the front is more advantageous to use. Typically, in order not to miss the notification, to avoid scratching the screen, people like to place your screen up. Previous put solar on the back does not conform to user habits, could not get enough energy.
From France, AIX in Provence solar technology startup SunPartner the same study Panel, is different from previous, SunPartner technical trickery, ripe, soon took the can. Speck iPhone 4 Case
SunPartner product ideas as shown in the following figure, the standard PV modules arranged in the form of stripes, alternating stripes into a flat and transparent thin films, topped with a layer of waves lenses. Due to light refraction principle, lens will render the content behind the transparent film zoom out, narrowing the PV module display. When the sun light, lenses allow focusing the light on PV modules.
This approach using optically "trick", bad obviously, that can't be 100% transparent, can currently only be 82% transparent, can be 90% in the future, the company has more than 30 patents.
SunPartner claimed that the glass cell phone battery life can be increased by 20%, about 2 hours of battery life. Resulting cost is US $ 2.3, currently and 3 handset manufacturers, is expected to list in early 2014. Wmpoweruser says Nokia is one of them.
Use screens to make the charging components, it is a great idea and put it on iPad, Kindle such effect will be more evident on the big screen, perhaps we will soon be able to see the device listed.
