This will be the windows of the future

This team of Korean scientists has opened the way to create the windows of the future, capable of producing solar energy

It is not easy to create photovoltaic panels that are transparent. And this is, of course, the key to windows. In the very nature of these architectural elements is the power to see through them. Sunlight has to pass, one way or another. A team of Korean scientists has taken a decisive step towards this type of crystals, called to ground the windows of the future.

Over the past few years we have seen some outstanding solar window projects. And it is that the height of skyscrapers in cities offers a greater opportunity than that of rooftops. Cities now grow vertically. There is the largest area to cover with photovoltaic panels. Some shuffling performance indicates the generation of 30W per square meter.

The team of Korean scientists has improved the previous models. Its system allows the creation of transparent solar panels, of proven effectiveness and at a moderate price. They have done it through the drilling of tiny holes in crystalline silicon panels. This allows the passage of light. In other models, when the solar radiation hit the crystals the luminosity took on a reddish hue.

In this way the reddish tone is avoided, while the holes are so small that the human eye does not detect them. The team is convinced that it is the best existing solution to create solar energy producing crystals. A more than desirable option for the windows of the future. The growth of cities will boost the construction of tall buildings, some of them completely glazed. The potential area to capture solar energy is huge.

The windows of the future, more than solar energy
The production of solar energy will be one of the characteristics that the windows of the future have. Undoubtedly it is a quality they must have to ensure the energy efficiency of buildings. We are not talking only here about the reduction of consumption but of a help to the generation.

But when talking about generation, the first point is often overlooked. The reduction of consumption is achieved with other formulas. At MIT they have already worked on this determining factor for energy efficiency. They managed to create crystals that reflect the light. They do it in such a way that when they get too hot they get dark. This stops the thermal radiation and prevents the building from heating.

It is a way to maintain a pleasant temperature in summer, when the sun hits with all its rawness. Due to the need to have sun in winter, so that the interior of the buildings is heated as much as possible, in summer the use of the air conditioner soars. This way you could save on this resource, which would mean a reduction in energy expenditure. Although it is possible to think that the nature of the solar crystals would allow to stop the heat transfer. Thus, the two solutions would offer two different options.
