Spherical solar panels has surpassed traditional in all respects

Scientists from the Scientific-technological University named after king Abdullah (Saudi Arabia) have developed a promising design of spherical solar cells. They proceeded from the concept that such a fully focused design, as opposed to the standard flat panels to collect the light, wherever he came. Including diffused and reflected light without the direct rays of the sun.

To reduce the cost of device, the Foundation took the model panel, in which the laser and ion etching deep cut grooves in the outer silicon layer. Next panel gently bent along the lines of the slits, giving them a semblance of segments of the sphere. This procedure led to the destruction of 15% of the light-absorbing surface, but the loss was compensated spherical battery showed 24 % increase in output power for the direct lighting lamp that imitates the sun.

Then it turned out that as the heating with the lighting spherical design better heat dissipation, which increased its advantages over the flat analog on 39 %. The best results were obtained in experiments with diffused light, no direct light on panels. Depending on the type of reflecting surface such as paper, metal or sand, the efficiency of the spherical elements were 60-100 % higher than flat. And it turned out that they deposited less dust.

An additional advantage of spherical structures in the absence of the rotation mechanism, without the need to deploy after the Sun. Also, spherical and simple curved solar panels can find application in architecture as a functional and decorative elements of the facades. But first we must test this new technology in open terrain and in different geographical locations.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Looks like a screwdriver of the XXI century

Recently Techcult wrote about the drill of the XXI century with a touchscreen and lasers. But the screwdriver is traditionally considered to be more simple, reliable and very straightforward tool. What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]
