Solar window shade

    The idea is to create solar window shade that will harvest the sun during the day and use it to power its OLEDs at night.
    The shades will be made of a semi-translucent, flexible fabric that will allow the sunlight to gently seep in. The integrated solar cells will block the sun while harnessing its energy, which will power the leaf-shaped OLED's. A central cord will control the blind, allowing it to be opened, and the whole shade can be easily rolled up for storage.
