Scientists Showcases Nanotechnology Based Low-Cost Solar Cells

The more extended the light spends inside the solar cells – the more prominent its possibility of getting ingested.

A group of researchers at Stanford University, including an analyst of Indian starting point, has indicated how nanotechnology can be utilized to make crystalline silicon (c-Si) thin-film solar cells that are more proficient at catching solar energy.

The revelation can diminish the cost of solar energy creation internationally, they noted. Dr. Shrestha Basu Mallick, working with her counselors Dr. Mark Brongersma and Dr. Peter Peumans, built up another technique for creating a less expensive and more proficient solar cell.

The group utilized optical displaying and electrical recreations to demonstrate that a thin-film crystalline silicon solar cell with a 2D nanostructure produced threefold the amount of photograph present as an unstructured cell of a similar thickness.

This is on account of the nano-organized surface traps approaching light more adequately making it invest more energy in the silicon material. The more extended the light spends inside the solar cell – the more prominent its possibility of getting ingested.

“Light absorption in crystalline silicon solar cells can be significantly enhanced by nanostructuring and this reduces the thickness of silicon required,” said Dr. Basu Mallick. “This is important because it helps countries be competitive against imported cells and paves the way for new solar applications such as flexible or transparent cells,” she added.

The disclosure uncovers a basic strategy to enhance the productivity of all silicon solar cells. The work was distributed in the journal Optics Express and has collected near 200 references including various book parts.
