Solar Nokia difficult
By Asha

Nokia still has the largest market share in India.  And for a number of reasons, like all its rivals, has invested a lot in solar energy to charge phones.

Nokia’s research project on phone charging using harvested solar energy has now been completed. So can the sun be relied on to charge your phone?  Nokia has published its research

“
The tests showed that charging a mobile phone by simply using a solar charging panel on the back cover is possible but challenging.

When carefully positioned, the prototype phones were able, at best, to harvest enough energy to keep the phone on standby mode but with a very restricted amount of talk time. This means there’s still some way to go before a workable and care-free solution is achieved. The most substantial challenge is the limited size of a phone’s back cover, which restricts the extent to which the battery can be charged. What’s more, to ensure mobility, it is essential that the phone’s weather protection doesn’t cover the solar charging panel.
