Organic photodiodes on newspaper

We report on the fabrication and characterization of organic photodiodes deposited on ordinary newspaper sheets. Parylene acts as water and chemical barrier layer, an ORMOCER layer serves as an excellent smoothing and base layer for the diodes. which correspond to classical Tang-type bilayer cells. The photodiodes show excellent diode behaviour in current-voltage measurements of the devices under dark and illumination I conditions. The spectral response covers the UV and visible spectral range.
