A paper solar cell circuit is shown powering an LCD clock when illuminated. The entire integrated paper photovoltaic is then fed through a roll-to-roll office laser-jet printer. The resulting ink spells MIT on the device side of the paper array, which then continues to power the LCD clock. The clock circuitry is shown at the end of the video, which is powered by the photovoltaic alone and regulates a constant voltage to the display for variations in light intensity. The paper photovoltaic array is illuminated from below with simulated solar illumination.
