Kyocera demonstrates smartphone with transparent photovoltaic layer




Kyocera at the Mobile World Congress a prototype of a mobile phone shown in which the screen can partly supply the battery with a transparent layer solar cells. The technology can also be used for other mobile devices such as e-readers and feature phones.The so-called Wysips Crystal technology , with transparent solar cells are packaged in a 0.1mm thin layer of film, developed by the firm Sunpartner. The film can be placed either before or after the LED panel and would hardly affect the image quality, the low is 90 percent transparent and also the viewing angles are not smaller according to the manufacturer.

However, the picture is indeed negatively affected by the additional layer, observed Mobile Geeks at the MWC show floor in Barcelona. The solar cells or did their work: the phone was continuously loading, unless the user kept his hand above the screen. Sunpartner claims that the solar cells in practice be able to generate peak-5mW per square centimeter provided that there is sufficient light falls on the screen.

Kyocera and Sunpartner claim that the displayed technology can make an “infinite” standby time possible for smartphones provided they receive adequate light. However, the solar cells will supply enough current to operate a used smartphone again fully recharge. Batteries in mobile devices such as e-readers and some feature phones would be possible without recharges can continue to work through the outlet.
