Absorbs solar energy with glass doors

Glass-coated coatings are one of three groundbreaking inventions, promising to potentially reverse the world of renewable energy.

Power generation coating for glass doors

There is one thing that ordinary people rarely think about, that is the number of glass windows that exist in modern society. This life seems indispensable to the presence of physical forms such as glass or glass. In the past, scientists have yet to find a way to incorporate solar cells / batteries into a form that can see through. Now, the team at Columbia, USA, has invented a transparent coating that can provide electricity for glass.

Rotating design for solar battery

A painful problem in extracting electrical energy from electrical devices, is the heat generated during this process. This is also the reason why gas-powered cars must have radiators and continuous cooling water circulation pipes in the vehicle's apparatus. Extracting electricity from solar energy also faces similar difficulties, where excess heat from the sun can break or damage the panel bar in short periods of time.

V3Solar offers an ingenious and simple solution to this problem. The company has created a three-dimensional control panel, rotating automatically using its own energy. This novel design absorbs energy efficiently from the sun's rays by up to 20% higher than traditional panel design, while reducing heat. This innovation promises to reduce the cost of solar energy to a lesser degree than the energy generated from coal and hydropower.

Inspired by moths

Thin film photovoltaic cells have been around for a long time, but the effectiveness of this technology is limited, because the fact that many layers of thin films are stacked on top of each other will produce reflected light that reduces the amount of electricity that can be declared. waterfall. Thanks to new achievements from researchers in the state of North Carolina, USA, this problem may no longer be a hindrance to scientists.

After studying non-reflective coating on the eyes of butterflies, scientists have found a way to reproduce the effect on thin-film solar cells. As a result, energy loss due to reflected light is reduced to about 100 times.

"We are inspired by the eye surface structure of moths. Being evolved to the point that this surface has high anti-reflection properties, so butterflies can use the amount of light even if only very small are available to look in. Darkness, " said Dr. Chih-Hao Chang, associate professor of aerospace and mechanical engineering in North Carolina and co-author of the study.

"By imitating that concept, we have developed a nanostructure that significantly reduces energy loss caused by thin films , " added Dr. Chih-Hao Chang.
