New breakthrough in graphene technology improves solar efficiency by 90%

Graphene is a two-dimensional carbon film that is only one atom thick. Carbon atoms are connected to each other in a hexagonal grid. It has always been known for its excellent electrical conductivity and mechanical strength, but its poor light absorption ability can only absorb about 2.3% of the incident light, so it is not suitable for making solar panels.

Recently, researchers at the University of Surrey in the UK have been inspired by the moth's eyes. Through the nanotexturing technology, the graphene surface can be textured and the light absorption capability of graphene can be increased by 90%, thus developing a nanometer. Grade ultra-thin graphene materials.

Like moth eyes, this material also has a micro-structure that reduces light reflection and increases light absorption. Also with moths to see things at night, solar panels coated with this material can absorb very weak light. Researchers also said that this material is expected to be applied to the Internet of Things such as "smart wallpaper".

CCTV News reported that a company in Shandong used biomass derived from corn paste to extract graphene materials. Compared with the conventional graphene processes and materials, the cost was reduced by 200 times. The application of this biological material is to solve the problem of mineral materials. Mining also gives full play to the advantages of resource recycling. It can be foreseen that the era of biomass graphene in China has come. Combined with the invention of new technology from British researchers, solar energy will become another inexhaustible new environmental protection resource in the near future.
