New type solar cells

Researchers from the University of North Carolina have inspired sunflowers to design higher-efficiency solar cells.

Accordingly, they focus on solar energy through nanostructured petals that act as germanium sulfide (GeS).

Ultra-thin petal architecture will help storage devices and energy storage devices operate more efficiently in a small space but with a large surface area.

Petals for solar cells are formed by passing GeS powder to the heating device. When evaporated, it will migrate to a cooling system that forms layers 20-30 nanometers thick and about 100 micrometers long. In structure, they overlap like carnations or marigolds.

GeS is a low-cost, low-cost semiconductor material for the environment. Its nanoparticle structure makes it a potential application not just in the field of solar power.

Thanks to its slim, large surface area, it will greatly increase the capacity of the current lithium-ion battery. According to Dr. Linyou Cao, the new structure of GeS can help power the supercapacitors and other energy storage devices.
