New technology allows solar cells to be more colorful

Under the current conditions, finding and using other sources of energy to replace fossil fuels is an issue that is being put on top by all mankind.

>>>New battery technology has a long life span from wood and sodium

There have been many solutions given such as wind or water power, however, the most promising and safe method is probably still using available solar energy.

However, for some people, price is not a problem, but what they worry about is aesthetic problem. Knowing this, scientists at Fraunhofer Research Institute in Germany are working hard to create a new technology that will make solar panels of different colors to suit their needs. each homeowner's demand.

These solar panels consist of a silicon substrate just a few micrometers thick that absorbs light and turns them into electricity. A transparent insulating layer was placed on the top and there was a nanomen of 100 nanometer thick oxide coating on it.

Oxides act like the second semiconductor layer, which is responsible for ensuring that as much light as possible can touch the silicon piece below. This layer is also a major element in changing the color of the battery array. By changing the physical thickness of transparent conductive oxides, the surface of the battery has a different optical refractive index, resulting in different colors.

You may be wondering if such a color change would make the battery work less efficiently, the answer from the scientists is not at all, not at all. The light particles they studied did not seem to be affected by the thickness of the conductive layer, the efficiency and power remained the same.

In the future, this study will contribute significantly to beautifying the battery or even allowing us to create battery arrays with a more complex design. The solar panels on our roof in the future will probably not be an object that can cause eye trouble like now, or even, they will be integrated directly into the structure of the roof or one. somewhat like a balcony at your house.
