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.
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.
