As smartphones screens get bigger and display resolution scales new heights, it has increasingly become difficult for phone manufacturers to maintain an optimum balance between features and battery life. From a time when we were little worried about the battery life in a phone, we have reached a stage where we would be happy to see a modern smartphone last even for around 10 hours – that too with nominal usage. The exponential growth in the processing prowess and graphical abilities of the modern smartphone is in contrast to only nominal improvements that have been seen in battery technology. With no improvements in sight, companies seem to be treading other paths to solve this problem.
Chinese communications giant TCL – who owns Alcatel has partnered with French company SunPartner to come up with a technology that would empower your smartphones with the ability to charge by itself – using embedded solar cells. Now, contrary to what you think, this wouldn’t mean sticking the back panel of the phone with ungainly solar cells. That has been thought of before and has been discarded long ago for being too cumbersome. Instead. the companies are working on a solution that would make the large touchscreen displays of today act as solar cells themselves. The force behind the idea is something known as Wysips (What You See Is Photovoltaic Surface) Crystal technology into which is basically an ultra-thin transparent film which is capable of drawing power from both natural and artificial lighting. The best thing about this film is that it could simply be amalgamated on to the touchscreen and no one would even notice! As expected, the company behind the technology is SunPartner who had demoed the same at the CTIA Wireless earlier this year.
Now, before you start stalling your next mobilephone purchase in anticipation of getting yourselves a phone that can charge itself, let me warn you that at this point in time this technology is still in its budding phase and is only being tested. It would be quite sometime till this thing becomes mainstream stuff.
