Ubiquitous Energy being absorbed. Developed from research done at Massachusetts Institute of Technology (MIT) they have developed organic photoactive materials (organic photovoltaics, OPVs) that allow visible light to pass through its technology but selectively absorb the light from the invisible part of the spectrum, near infrared (NIR) and ultraviolet (UV) light. They call this technology ClearView power. ClearView Power is an invisible film less than 1/1000 of a millimeter thick that can be put onto any surface and generate energy without with out affecting the material beneath it. Specifically they are trying to capture all of the photons of ultraviolet and infrared
Invisible ink of these papers prevents ink from being absorbed deep into the paper and it is easily visible, especially if the paper is examined under glancing light. There are, however, commercially available inks for non-porous surfaces that are only visible under ultraviolet light and are otherwise virtually invisible on such surfaces. Using either ultraviolet light or an iodine fume cupboard, messages can be quickly screened for invisible ink and also read without first permanently developing the invisible ink. Thus, if a censor uses this method to intercept messages, the letter may then be sent to the intended recipient, who will be
