The existing photovoltaic module has to be installed at the rear of the product, or, at the place which is not the screen. Therefore, it is inconvenient in use and in charging the battery.
If the photovoltaic module would be installed at the lower part of the transparent OLED, it can receive sunlight and be charged without having to turn over the product. Therefore, it can be charged while moving around with the mobile device. When the product is in use, the module will receive the light energy from the OLED and recycle the energy.
