Nano flakes may pave way for perfect solar cells

Copenhagen, Dec 19 (ANI): The future of solar cells may lie in a new material called nano flakes, which may revolutionise the transformation of solar energy to electricity, thus enabling households to save money in the future.

Martin Aagesen, a PhD from the Nano-Science Center and the Niels Bohr Institute at University of Copenhagen, is researching upon this new material.

We believe that the nano flakes have the potential to convert up to 30 per cent of the solar energy into electricity and that is twice the amount that we convert today, said Martin Aagesen.

Martin found this new and untried material during his work on his PhD thesis.

I discovered a perfect crystalline structure. That is a very rare sight. While being a perfect crystalline structure we could see that it also absorbed all light, said Aagesen. It could become the perfect solar cell, he added.

Less than 1 per cent of the world’s electricity comes from the sun because it is difficult to transform solar energy to electricity.

But if researcher Martin Aagesen’s future solar cells meet the expectations, both the economy and the environment will benefit from the research. In fact, the new discovery may be a huge step towards boosting the exploitation of solar energy.

The potential is unmistakable. We can reduce the solar cell production costs because we use less of the expensive semi conducting silicium in the process due to the use of nanotechnology, said Aagesen. At the same time, the future solar cells will exploit the solar energy better as the distance of energy transportation in the solar cell will be shorter and thus lessen the loss of energy, he added.
