Energy is needed in almost everything. No, I am not talking about the one in your body, but electricity, and the one which is used to propel vehicles. In the good old days, this power was generated with the help of non-renewable or non-sustainable sources such as coal and other fossil fuels. But now, the things have changed and also technology. Now people are fairly aware and inclined about sustainable energy.
In this blog, we will talk about one of the increasingly popular sources of producing sustainable energy, i.e., ultra-thin solar cells.

Solar Energy Getting Popular in Current Scenario
In the past decade or so, there is no doubt that a lot of heed is given to the production of solar energy for everyday use. It is getting increasingly common sight to see ultra-thin solar cells mounted on roofs of both residential as well as commercial buildings. This is a good step toward attaining sustainable energy, as the sun will not exhaust with time as opposed to other fossil fuels.
New Variant of Solar Cell Developed
It is not too much to say that we are living in the world of scientific advancements, where there is an advancement, every other day. This holds true in case of solar cells as well.
Constant research has given a fruitful result, and a solar cell is made, 1 micrometer thick, which can convert around 67% of sunlight into electricity.
This newly developed solar cell is around 100 times thinner than a sheet of paper, and can further improve to 33.8mA/cm². This would make a photovoltaic cell with over 20% efficiency, roughly in line with larger panels.
The developed ultra-thin solar cells make use of correlated disordered hyperuniform patterns. These let over double the solar light absorption of a uniform silicon slab.
The test cells were made with the use of ultra-thin crystals of silicon, designing these with patterns with the help of etching fluids and electron beam lithography. The thickness of the ultimate product varied slightly from the testers of approximately 1.18 micrometer across areas of 1.3×1.3 mm² or 4.8×4.8 mm².
Discovering the Potential Ultra-Thin Solar Cells
There is a lot of talk that what is the true potential of these solar cells, and to put all that to a close enormous potential for using ultra-thin solar cells.
They are particularly useful in space and could make a new extra-terrestrial project feasible. Due to the fact that a lot lesser amount of silicon is used, they are not that costly as compared to some of the conventional solar cells. Not only that, there will also be more and more benefits from the IoT and to create of zero-energy buildings powered locally.
It is because of the recent and regular developments in the technology of solar cells, the newest version, ultra-thin solar cells are now growing in demand day by day all over the world.
