Transparent solar films add 20  to your phone's battery life on the cheap

The French from SunPartner are having a very pragmatic approach to the promising field of transparent solar cells that can be used as a screen cover, charging our phones even while in use and off the grid.

Instead of the complex and expensive projects from the likes of MIT and UCLA that are trying to weave miniature solar cells into the touchscreens themselves, or other projects that harvest the light leaking from OLEDs, SunPartner is just combining traditional with transparent solar cells.

The visible traditional solar stripes are then being hidden vie an add-on cover with numerous lenses that distribute the light in a certain way. Currently the company has achieved 82% transparency, with future prototypes expected to hit 90%. The CEO has been in the Silicon Valley recently, demonstrating the product to the mobile talent there.

Apparently the solution adds about 20% to your battery life with normal usage, and can also power the phone completely when standing by in daylight, thus being gentle on your juicer, no matter how many mAh the manufacturers manage to cram in. SunPartner says that three phone makers have already expressed interest and are working with prototypes of the technology.

I stopped caring about battery life since getting a note 2. I am a very heavy user of my phone during the day and night and it easily lasts me the day with plenty of charge left when I plug in to go to bed. Includes a few hours if browsing, taking pics and watching youtube.

my gs3 makes it a day if I go easy. but in July I take groups camping and we go 3 to 5 days at a time with out power. Anything that can extend the battery is good for me. between this and my yard light solar panels rigged to portable juice pack I could maybe go the entire time with my phone on. or at least in standby.

So, how are they charging the battery? I'm assuming inductive but that seems like it would take forever just using solar power.

It isn't meant as a primary charger. The approach or thought is to increase the duration of your battery as you use it throughout the day or lighted environments.

I'm always trying to find thin sheets of scratchable plastic to put on top of my Gorilla Glass screen.... This could be the answer!

I'm really not a fan of charging my phone constantly. Every battery has it's own charge cycles, so imo it might affect the battery's endurance or something...
