Thermochromic Vanadium Oxide Coated Window Saves And Generates Energy

The never ceasing diligence to figure out ways of saving energy is what makes Chinese Scientists helped build a new smart window that may eventually reduce heating and cooling costs for apartments and hotels.

The never ceasing diligence to figure out ways of saving energy is what makes Chinese Scientists helped build a new smart window that may eventually reduce heating and cooling costs for apartments and hotels.

The new smart window can both save and generate energy unlike conventional smart windows and solar cells that can’t be combined into one device for energy saving and electricity generation.

 Thermochromic Vanadium Oxide Coated Window Saves And Generates Energy
A hybrid smart window device that can achieve energy savings and generation was designed based on a sandwiched composite film that was composed of dispersed VO2 particles and a polymer matrix. This device can temperature-dependently regulate solar heat and generate electricity using a solar cell positioned around the glass panel and powered by VO2 particle-scattered light, simultaneously remaining visible transparency. | Credit: J.

Y.F. Gao of the Chinese Academy of Science apprised that today’s smart windows’s scantiness in regulating heat and light from the sun results in loss of potential energy. Also, traditional windows cause heat to escape buildings in winter, which is quite an adverse situation and unwanted Sun’s rays in summer.

Scientists and engineers have long been battling to incorporate energy-regulating solar cells into window panes without effecting their transparency. Now, the issue has been resolved as the team led by Y.F. Gao discovered that Vanadium oxide (VO2) can be used as a transparent coating to regulate radiation from the Sun.

As told in the journal Nature – a VO2 film can respond to the environmental temperature to intelligently regulate infrared transmittance while maintaining visible transparency, and can be applied as a thermochromic smart window.

  1. It’s great to see that people are finding solutions to our needs for energy. It would be nice to be able to buy this sort of thing at a reasonable price. I hope they can come up with more stuff like this and get it out to the general public! Solar power is a fantastic resource and it would be really nice if we could figure out more ways to use it. To make it truely competitive with oil/gas/coal.

    1. Yeah, they learned it the hard way and this is just a step forward to save energy. Also, they will definitely find an alternative for that one, too. We will just have to wait and see what comes around and what goes around.
