  • Patent number: 11152888
    Abstract: Embodiments of the invention generally relates to photovoltaic, thermophotovoltaic, and laser power beaming devices which convert solar light, thermal radiation, or laser radiation into electric power. Said devices have a reflective interference “greenhouse” filter placed in front of a semiconductor cell and a reflective mirror on the back of the cell. The front filter is transparent for high energy (short wavelength) photons, but traps low energy (long wavelength) photons emitted by photocarriers accumulated near the semiconductor bandgap. In the optimized PV device, the chemical potential of photoelectrons near semiconductor bandgap exceeds the chemical potential of photoelectrons above the photonic bandgap established by the filter (i.e., the device is in chemical nonequilibrium). The greenhouse filter reduces the emission losses, decreases the semiconductor cell thickness, and provides PV conversion with reduced nonradiative losses.

  • Patent number: 11152621
    Abstract: Since a surface of the artificial graphite of the negative electrode active material according to the present invention is modified with nitrogen, dispersibility in an aqueous system may be improved and accordingly, affinity between a binder and the negative electrode active material is increased to increase the adhesive strength of an electrode. Also, since the surface of the artificial graphite is modified with nitrogen, there is an effect of maintaining a high battery capacity. Furthermore, in the method of preparing a negative electrode active material according to the present invention, since an oxygen-containing functional group is connected to the artificial graphite by a mild oxidation process, the nitrogen may be easily attached to the artificial graphite so that the negative electrode active material becomes an electrical conductor by maintaining original crystallinity while having a hydrophilic property. Thus, excellent battery efficiency may be achieved.
