Thanks Elizebeth for such an interesting post, I can see how much technology is advancing its really amazing that one can extend the battery of cellphone through solar panels , as mobile battery charging is  really  very big issue these days . If unfortunately one has to make an urgent call and battery gets discharged then you have to stop and charge the mobile phone however solar panels will extend the battery on go thats really great it wont waste ones time .

Hey Elizabeth, what if they could make clothing out of it. Not like we have today, but like just normal clothes. All day in the sun charging your suit. Sorry, I tend to think outside of, um, whatever box it is people live in. Engineers should. :) One day we'll be walking around charging all the stuff we have with us.

Cadman, I think such thin solar film technology can be used for recharging most of the handy devices, especially the commonly using devices like watch, phones, tablets, laptops etc.

True Cadman There is a point, because of the see threw feature it will not affect the appearance of the clothe.

Near future we will have the wearable solar panels which will charge the smart phone or the tablet etc while on the walk without having any appearance issue at all.

Pubudu, that's a great idea. For wearable devices, obliviously there should be some source to derive power and if that source is solar energy, that's great.

I agree, that is a great idea, Mydesign and Pubudu, and it's probably not so far off in the future as we think. Wearable solar panels as well as energy-harvesting clothes are definitely the way of the future.

Elizabath, wearable solar panels also required some energy processing and storing mechanism. So you meant that such devices are also wearable.

@Mydesign true that there should be a way of storing the power
I believe that that will be a part of the hand bag or it will be able to plug to the laptop or the phone when we carry those with us.

Pubudu, no doubt, one day that will also happen. But I would like to see something think thin PV films, which can stick over any surface t power the hand held devices.

Mydesign,

I agree. This solar panel design would be great for wearable devices because of its small size. Imagine being able to have a wearable device where batteries would never have to be replace. Makes good design since.

Your correct. I was speaking on how regular batteries would not need replacing immediately because of the solar charging incorporated with the wearable device.

Mrdon, am not clear about it. Same battery can be use for storing both solar and electric energy. What I meant is about foldable and wearable batteries.

Ok, its not the power storage capabilities of the battery but the ability to package it into a battery that is wearable and can be folded. Got it!

True Cadman, I also see a lot of application of this innovation.

I believe that this will be more suitable for the vehicle windows and the window glass as you mention.  But sometimes I feel that cost factor would be a barrier for this.

It's pretty cool, isn't it, Ann? And if it actually works on devices, this could be a real game-changing technology. I find the work being done to create solar panels out of many unconventional things really exciting. It just makes perfect sense, too.

"The day when your smartphone screen is also a mini solar panel may not be far off, thanks to new two-layer see-through solar film developed by researchers at the University of California Los Angeles (UCLA)."

Elizabeth, that's a good thing so phone also can be recharged through these screen and hence no more battery drain.

Hi, Mydesign...yes, I think one day if this technology takes off and advances that will be true. It would be great also if it could actually mean a battery-less mobile phone, but that would probably be way far off in the future. Or maybe not, seeing as how fast technology moves these days!

I am imagining that one day one of these energy-harvesting systems will be strong enough to power a mobile phone, whether they harvest from solar, vibration, the heat of human touch--whatever! It seems like this technology is progressing quite fast so someone far more intelligent than me can come up with something soon.

Elizabeth, the seed is good and I think research community had start working on that. Alternate energy sources (solar, vibration, wind etc) are the only reliable energy source for future.

I agree, MyDesign, the way forward is to take the energy that can be generated from so many sources other than chemical-based batteries or electricial wires. I think the demand for energy is growing at too fast a pace for typical means to constantly support it. Still, innovations in new battery designs also will keep batteries in play for the forseeable future.

Elizabeth, you are right. when new technologies are deriving for various applications from alternate energy sources are deriving,  similar inventions has to happen in preserving/storing that energy too. both has to be synchronized, otherwise we won't be able to derive the full benefit of new technology.

Exactly, MyDesign. Energy-harvesting is really growing but it's not like it's suddenly going to replace batteries or traditional means of power. I think the research into both areas, as you point out, has to be on parallel tracks and I also think the two are complementary, not necessarily competitive, technologies. That's the case with some of the research, in which there is a harvester that does some of the work while batteries do the rest.

Elizabeth, great piece! It's great to see Prof. Yang pushing ahead in a crucial area of energy harvesting. When we did the Drive for Innovation project, we spent time with him in his office at UCLA and got some insights into the challenges he's confronting in broad spectrum solar cell research. Here's a link to the story and the video interview we conducted is below:

spectacular Innovation, who would have ever imagined the solar cells to be transparent. Its a great advancement. The present problem, that many smart phones are facing is there short battery time. The amount of usage requires them to have a better battery time. If this solar film can increase the battery time without adding extra material/weight to the phone, than it is definitly worth to be in the market.

Using this for office windows seems more realistic than cell phones.  How much sun does the average cell phone really get?

I hope it makes its way to the automotive industry too.  Five years isn't far off.

I see your point, NadineJ, and agree windows are definitely a place where this technology could be utilized more. But for charging a cell phone itself I think this technology can be useful. I agree, though, mobile devices normally don't get too much sun and actually if they do, they don't like it much and overheat! If the mobile device technology could be suited for catching the sun better than this would really work.

Hey Elizabeth...

I'm always interested in solar cell updates.

On the otherhand, I had an allergic reaction to my cell phone about 10 years ago. The only time I had one since was when my daughter was about to have her most recent baby... She bought me a track phone with $10 worth of time on it and told me "it will ring someday soon... answer it cause it will be the baby". After that call I put that phone down like it was a rabid animal... by denying it electricity.

Recently, circumstances have dictated that I get over my distain for cell technology. I bought a base model at an airport when I was overseas in Nov  2012, and I now carry a StupidPhone® everywhere...

One thing that I am relearning is just how often they need to be charged (part of my original allergy BTW). If setting the phone on my desk, or a table in a well lit room would add say 5 to 10 minutes of life per hour of charge time... at that rate it will absolutely help. Even if it just maintained the charge during 'wait time'...

It may not be worth the added expense yet, but once the cost of the windows drop, or... if this was the only way to re-establish contact with emergency help in a disaster situation (I feel a short story idea coming on)...

Thanks for your comment, Ralphy Boy. I am amazed you could've survived without a mobile phone for any long length of time, though I suppose it would be refreshing. Yes, they still take a long time to charge, but there are a number of efforts to improve battery life and recharging times for mobile devices, work that I have written about here on this site. In particular work around lithium-ion designs seem to be the way forward. Energy-harvesting technology could be a good option for charging and power in the future, but that seems to be a bit of time away. Good luck with your phone!

Thanks for the feedback, the TOPV transparent organic photovoltaics , that we are heavily involved with under licence with UCLA , has made great progress over the last 12 months, still challenges to bring to Market , but we well funded, and see the next generation cell phones to self charge using the Technology, but our goal is TOPV glass, to help power homes and offices around the world through light., clean green and affordable glass.will solve many of our energy needs in the near future .transparent glass that generates enough electricity to power a building is a game changer .we see it as the DNA of a green world

That's a good goal, TOPV--as you say, this has the potential to provide power for buildings in an unprecedented way and could save people a lot of money. The potential for mobile devices is relevant as well, but I think the larger scale is where the real value is. Good luck with the project and getting the technology to market.
