Scientists at Michigan State University are coming up with a totally transparent solar concentrator, that may transform any kind of windowpane or sheet of glass ( such as your smartphone’s display screen ) into a photo voltaic solar cell.


As opposed to other “transparent” photo voltaic that we’ve seen on previously, this one entirely transparent, as you can see in the photographs. As per Richard Lunt, who led the analysis, the team are assured that the transparent solar panels can be effectively implemented in an array of configurations, from “tall buildings with lots of windows or any kind of mobile device that demands high aesthetic quality like a phone or e-reader.”


Technically, a transparent solar panel is a thing of an oxymoron. Solar cells, in particular the photo voltaic type, make energy by soaking up photons ( sunlight ) and changing them into electrons (electricity ). If a material is crystal clear, however, by description it implies that all of the light passes through the medium to strike the back of your eyeball. Because of this previous transparent solar cells actually have only been perceived as partially transparent or you can say translucent — and further they cast a colorful shadow as well.


The organic salts absorb UV and infrared, and then give off infrared — processes that take place outside of the visible light spectrum, to ensure that it appears transparent.


To circumvent this restriction , the Michigan State research workers employ a fractionally distinct technique for accumulating sunlight . Rather than attempting to build a transparent photo voltaic cell (nearly impossible ), they use a transparent luminescent solar concentrator ( TLSC ). The TLSC comprises of organic salts that accumulate specific non-visible wavelengths of ultraviolet as well as infrared lights, which they after that luminescence ( glow ) as a second wavelength of infrared light ( moreover non-visible ). This discharged infrared light is directed to the edge of plastic, where thin strips of traditional photo voltaic solar cell transforms it into electrical energy. ( Research paper : DOI : 10 .1002/adom .201400103 – “Near-Infrared Harvesting Transparent Luminescent Solar Concentrators”)

If you take a close look, you can observe a few black strips along the rims of plastic block. Otherwise, however, the active organic material — thereby the greater part of the solar panel — is highly transparent.


Michigan’s TLSC presently has an efficiency of around 1% , however, they believe 5% should be achievable. Non-transparent luminescent concentrators ( which saturate the location in colored light ) max out at around 7%. Automatically these aren’t large statistics, yet on a much larger scaleeach and every windowpane in a house or work place block — the numbers mount up and makes up huge figure. Additionally, whilst we’re most likely not discussing a technology configured to always keep your smartphone or tablet functioning forever, substituting your device’s screen with a TLSC can get you some more minutes or hours of usage on a single battery recharge.

The researchers are positive that the tech can be scaled entirely from big industrial and commercial applications, right down to customer units, whereas staying “affordable .” So far , among the bigger obstacles to large-scale adoption of solar power is the invasive and unattractive nature of solar panels — undeniably, if we can churn out a considerable amount of solar power from linens of glass and plastic that appear like regular sheets of glass and plastic, then simply that could be a huge leap.
