Life time is a common challenge for all smartphones today. Compared with those cool new technologies, the battery is always playing behind the silent role of the old man, taking all the nicknames alone.
SunPartner, a French startup, wants to change this through their technology – solar cells on the phone screen to charge the phone, and they have developed a transparent film and put it into trial.
The new technology, called "Wysips (WhatYouSeeIs PhotovoltaicSurface)", is known as an "unprecedented technology" that converts light source into energy, whether natural or artificial.
Simply put, the technology is to hide the solar panel between the screen glass. It uses a transparent coating with a thickness of less than 100 microns on the screen of the mobile phone to capture the solar energy to charge the mobile phone, so that the mobile phone is in the daylight. You can get the power to support the talk time of about 30 minutes, and you can fill a mobile phone battery in six hours. After the photovoltaic material is attached to the screen of the mobile phone, it does not affect the display and use of the screen. While reducing the reflection of the sunlight, the screen can be seen more clearly, and the official conversion rate is about 10%. Mobile phone products can provide an effective way to increase battery life, allowing outdoor users to charge their phones anytime, anywhere.
At present, SunPartner's charging screen can achieve 82% transparency and is expected to reach 90% in the future. The current cost of this technology is very low, and it costs about 2.3 US dollars (equivalent to 14.1 yuan) for ordinary mobile phones. If used properly, such as when you put it on the table in the sun or when you walk out, you can increase the battery's power by 20%. Speaking of 20%, this number is certainly not enough to save stupid Earth people, but this will be the first truly consumer-grade battery technology.
SunPartner's products are expected to come out next year. Relevant sources revealed that they are currently working with well-known manufacturers including Nokia, and the related products are not clear. It is estimated that they will have to wait for several years.
