Revolutionary Bifacial Solar Cells with Carbon Nanotubes

• Revolutionary bifacial perovskite solar cells with carbon nanotube electrodes offer high performance and cost efficiency, maximizing energy generation from all angles of sunlight.

Researchers from the University of Surrey, University of Cambridge, and several Chinese institutions have developed high-performance bifacial perovskite solar cells using single-walled carbon nanotubes as electrodes. These cells have a bifaciality factor of over 98% and a power generation density of over 36%, thanks to the high transparency, conductivity, and stability of the carbon nanotubes.

The bifacial cells can harvest sunlight from both front and back panels, generating more energy regardless of the angle of the light. The team also created flexible, all-carbon-electrode-based devices with a high power-per-weight value of 73.75 W g−1 and excellent mechanical durability. Additionally, the bifacial devices have a lower material cost compared to conventional monofacial perovskite solar cells.
