Transparent polycrystalline cubic silicon nitride : Scientific Reports
Neat, but requires twice the pressure to make compared to diamond, then again it can work in a hotter regime. Good for engine optical monitoring ports?

Production of Flexible Transparent Conducting Films of Self-Fused Nanowires via ...
Launching silver nanowire suspension water out of a supersonic nozzle at a specific speed allows creating a transparent thin film mat on a surface, that fuses/evaporates on impact. The resulting thin film is transparent, conductive, and stretchable.

Light Harvesting: Near-Infrared Harvesting Transparent Luminescent Solar Concentrators (Advanced Optical Materials 7/2014) - Zhao - 2014 - Advanced Optical Materials - Wiley Online Library
So collects and redirects NIR to the pane edge,where it can be converted to other wavelengths (regular IR) for a solar power generator to consume. Does near infrared now, seems possible to also to UV as well.

Apparently they have somehow moved the display optics lens from an external lightguide prism/lens/optic that sits in front of the eye to a contact lens on the eye. Not the actual display itself though, like some form of transparent OLED printed on a contact lens (which unfortunately has data/power transfer issues).

[Column] Will Alligators Save Thin-film Si PV Cell Makers? -- Tech-On!
Sun Well Solar is claiming a 6% efficiency transparent thin film solar cell panel, and demoing as roofing on a greenhouse. 6% may not be so great, but if the costs come down via thin film roll-to-roll production, it may not matter so much.

[JSAP] Optical Fiber Turns Into Solar Cell -- Tech-On!
Interesting hybrid cascade/tandem solar cell architecture using fiber optics. The trick is to catch light bouncing in the fiber by dye sensitized solar cells mounted as a concentric cladding around the fiber. To get higher efficiency, have one band of cells of a length sufficient to cat most pounced light in a single pass, then have another band farther down the fiber optimized for a different wavelength for the second pass. You would have multiple bands from front to back with short wavelength stuff up front. Interesting that these guys are gunning for the near-infrared, as they use bounced light which doesn't suffer from transmittance problems encountered in transparent electrode TCO dye sensitized tandem cells which must pass through the first layer to reach lower layer cells.
