Organic PV offers exceptional advantages in form factor and cost while generating the highest energy harvested per day leading to the greatest energy payback.
In OPV the fullerene acts as the n-type semiconductor (electron acceptor). The n-type is used in conjunction with a p-type; either a polymer or other molecule (electron donor). Typically they are blended and cast as the active layer to create what is known as a bulk heterojunction. Fullerenes are used on their own or derivitized to increase their solubility and modify their electronic properties. The most commonly used fullerene derivatives in OPV applications are C60 and C70 PCBM. As the preferred n-type material, fullerenes can comprise up to 75% of the active layer by weight. The potential for increasing device efficiency through novel fullerene chemistries continues to expand. For example, alternative derivatives such as C60 ICBA and C60 OQDM have been shown to increase conversion efficiency by over 40% when compared to C60 PCBM in like systems. These and others are patented by Nano-C.
Demand for a greener alternative to fossil fuels has never been higher. This has sparked massive development in how to harness the power, efficiency and flexibility of carbon – the strongest, environmentally safe and most abundant element on earth.
By partnering with Merck and other industry leaders, Nano-C has developed the most efficient and cost-effective carbon-based fullerenic materials to power a wide range of applications. These materials are enabling companies to deliver breakthrough technology that can generate green energy and power our world into the next century. Featuring patented technology, Nano-C’s carbon-based fullerenic materials are inexpensive, printable, flexible, and tough enough to withstand extreme environmental conditions.
