Solar transparent coating allows all mobile phones to bid farewell to the charger
When using a mobile phone outdoors, the strong sunlight will turn some mobile phone displays into a mirror, making it impossible for people to read the text and pictures on the screen. Therefore, technologies such as anti-glare display and glare film have become necessary for many new mobile phones. The function, if let the mobile phone screen have the solar charging ability, what if the screen turns into a solar electric board?
Wysips from France demonstrated today at the CTIA exhibition a transparent photovoltaic film material that can convert light energy into electrical energy. Adding this film to the screen of a mobile phone can increase the solar charging function without affecting the display of the screen. In this way, when using the mobile phone outdoors, the mobile phone can be replenished with electricity, and the reflection of sunlight can be reduced to make it easier to see the screen.
In a nutshell, this technique involves the filtering of light on the surface of the lens. When the light emitted by the cell phone display and the reflected strong light pass through the film, the strong light is filtered and converted into electricity. The light visible to the human eye It can pass normally. This layer of film can be directly attached to the display and will be located below the capacitive layer so as not to affect the touch performance of the screen.
Wysips doesn't use a full phone for display, but you can see the obvious effect when you show it. You can see a voltage change from 1.2 volts to 2.5 volts with a piece of paper covering the screen. In fact, at the time of the demonstration, the film still had some influence on the brightness and sharpness of the display. Wysips stated that this is the prototype device of the old generation and that new devices will not be affected in the future.
According to the company’s introduction, the solar conversion efficiency of this film is currently around 9%. Although it is lower than the world’s highest conversion rate of 40%, it can effectively increase endurance for mobile phones.
