Researchers in Korea are exploring the technology in solar cells. The team has used the Dry-Wet Method to recover an original DNA lattice structure. The group then deposited the 2D double crossover tile-based arrangement safely on an organic layer.

Improved design

The DNA lattice was employed as an electron blocking layer in polymer solar cells, causing an increase of up to 10.2% in power conversion efficiency. Solar cells containing the artificial 2D DNA blocking layer showed a significant enhancement compared with conventional designs.

It is clear that the artificial DNA nanostructure holds unique physical properties that are extremely attractive for various energy-related and photonic applications.

The researchers presented their work in the journal Nanotechnology.
