Advanced Graphene Products to go public next week at the NewConnect market
Poland-based Advanced Graphene Products S.A. (AGP), a graphene flakes and sheet developer, announced that it will go public, with a listing on the NewConnect market, on November 29th.
AGP has an annual capacity of 100Kg for graphene flakes and 150 m2 of large-area graphene sheets. The company is currently preparing to launch a pilot sale of a graphene-based filament for 3D printing.
Researchers demonstrate how graphene can improve perovskite solar cells
Recent research has shown that the incorporation of graphene-related materials improves the performance and stability of perovskite solar cells. Graphene is hydrophobic, which can enhance several properties of perovskite solar cells. Firstly, it can enhance stability and the passivation of electron traps at the perovskite’s crystalline domain interfaces. Graphene can also provide better energy level alignment, leading to more efficient devices.
In a recent study, Spain-based scientists used pristine graphene to improve the properties of MAPbI3, a popular perovskite material. Pristine graphene was combined with the metal halide perovskite to form the active layer of the solar cells. By analyzing the resulting graphene/perovskite material, it was observed that an average efficiency value of 15% under high-stress conditions was achieved when the optimal amount of graphene was used.
Roadfill succeeds in raising funds for its graphene-enhanced road repair technology
UK-based Roadfill develops a technology that combines waste plastic with graphene that is used to repair roads, while cutting CO2 emissions and creating a circular economy. According to the company's research, its products reduce bitumen (heated petroleum) usage by up to 14%, and last on average 7X longer, which can cut costs for public bodies and businesses by up to 30%. The products can be more weather and pothole resistant, and give greater surface friction, reducing tyre fatigue and braking distances.
Roadfill is now raising funds in a successful crowdfunding campaign. The campaigns ends today, and the company already raised over £550,000 from over 600 investors, well over its original £350,000 target. If you are interested, hop over to Seedrs to check the company out - as you can still invest in it today.
