Windows Future

It is not easy to create photovoltaic panels that are transparent. And this is, obviously, the key to achieving 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 glass, called to found the windows of the future.

Windows Future

Over the past few years, we have seen some outstanding solar window projects. And it is that the height of the skyscrapers in the cities offers a greater opportunity than that of the roofs. Cities now grow vertically. There is the largest area to cover with photovoltaic panels. Some returns that are considered indicate 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 this by drilling tiny holes in the crystalline silicon panels. Thus the passage of light is allowed. 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 cannot detect them. The team is convinced that it is the best solution available to create solar energy-producing crystals. A more than desirable option for the windows of the future. The growth of cities will drive the construction of tall buildings, some of them fully glazed. The potential surface to capture solar energy is enormous.

Windows of the future, more than just solar energy

The production of solar energy will be one of the characteristics that the windows of the future have. Without a doubt, it is a quality that they must have to ensure the energy efficiency of buildings. We are not only talking here about reducing consumption but about helping the generation.

But in speaking of 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 light. They do it in such a way that when they get too hot they darken. This stops thermal radiation and prevents the building from heating up.

It is a way to maintain a pleasant temperature in summer when the sun hits with all its harshness. Due to the need for the sun in winter, so that the interior of buildings is heated as much as possible, in summer the use of air conditioning skyrockets. In this way, this resource could be saved, which would mean a reduction in energy expenditure. Although it is possible to think that the nature of the solar crystals would allow stopping the heat transfer. Thus, the two solutions would offer two different options.
