  • Patent number: 11916180
    Abstract: Narrow bandgap n-type small molecules are attracting attention in the near-infrared organic optoelectronics field, due to their easy tunable energy band with a molecular design flexibility. However, only a few reports demonstrate narrow bandgap non-fullerene acceptors (NFAs) that perform well in organic solar cells (OSCs), and the corresponding benefits of NFA photodiodes have not been well investigated in organic photodetectors (OPDs). Here, the ultra-narrow bandgap NFAs CO1-4F, CO1-4Cl and o-IO1 were designed and synthesized for the achieved efficient near-infrared organic photodiodes such as solar cells and photodetectors. Designing an asymmetrical CO1-4F by introducing two different ?-bridges including alkylthienyl and alkoxythienyl units ultimately provides an asymmetric A-D?-D-D?-A molecular configuration. This enables a delicate modulation in energy band structure as well as maintains an intense intramolecular charge transfer characteristic of the excited state.

  • Patent number: 11817524
    Abstract: Refractive optical element designs are provided for high geometric optical efficiency over a wide range of incident angles. To minimize Fresnel reflection losses, the refractive optical element designs employ multiple encapsulant materials, differing in refractive index. Concentrator photovoltaic subassemblies are formed by embedding a high efficiency photovoltaic device within the refractive optical element, along with appropriate electrical contacts and heat sinks. Increased solar electric power output is obtained by employing a single-junction III-V material structure with light-trapping structures.
